## Bilateral relations
### North and South America

| Country | Formal relations began | Notes |
| Argentina | 1823 | See Argentina–United States relationsArgentina was integrated into the British international economy in the late 19th century; there was minimal trade with the United States. When the United States began promoting the Pan American Union, some Argentines were suspicious that it was indeed a device to lure the country into the U.S. economic orbit, but most businessmen responded favorably and bilateral trade grew briskly. The United States has a positive bilateral relationship with Argentina based on many common strategic interests, including non-proliferation, counternarcotics, counter-terrorism, the fight against human trafficking, and issues of regional stability, as well as the strength of commercial ties. Argentina is a participant in the Three-Plus-One regional mechanism (Argentina, Brazil, Paraguay, and the United States), which focuses on coordination of counter-terrorism policies in the tri-border region. Argentina has endorsed the Proliferation Security Initiative, and has implemented the Container Security Initiative and the Trade Transparency Unit, both of which are programs administered by the US Department of Homeland Security/Immigration and Customs Enforcement. |
| Belize | 1981 | See Belize–United States relations |
| Bolivia | 1849 | See Bolivia–United States relationsThe United States and Bolivia have had a tradition of cordial and cooperative relations. Development assistance from the United States to Bolivia dates from the 1940s, and the United States remains a major partner for economic development, improved health, democracy, and the environment. In 1991, the U.S. government forgave all of the $341 million debt owed by Bolivia to the United States Agency for International Development (USAID) as well as 80% ($31 million) of the amount owed to the United States Department of Agriculture for food assistance. The United States has also been a strong supporter of forgiveness of Bolivia's multilateral debt under the HIPC initiatives. |
| Brazil | 1824 | See Brazil–United States relationsThe United States was the second country to recognize the independence of Brazil, doing so in 1824. Brazil-United States relations have a long history, characterized by some moments of remarkable convergence of interests but also by sporadic and critical divergences on sensitive international issues. The United States has increasingly regarded Brazil as a significant power, especially in its role as a stabilizing force and skillful interlocutor in Latin America. As a significant political and economic power, Brazil has traditionally preferred to cooperate with the United States on specific issues rather than seeking to develop an all-encompassing, privileged relationship with the United States. |
| Canada | 1926 | See Canada–United States relationsRelations between Canada and the United States span more than two centuries, marked by a shared British colonial heritage, conflict during the early years of the US, and the eventual development of one of the most successful international relationships in the modern world. The most serious breach in the relationship was the War of 1812, which saw an American invasion of then British North America and counter invasions from British-Canadian forces. The border was demilitarized after the war and, apart from minor raids, has remained peaceful. Military collaboration began during the World Wars and continued throughout the Cold War, despite Canadian doubts about certain American policies. A high volume of trade and migration between the United States and Canada has generated closer ties. The current bilateral relationship between Canada and the United States is of notable importance to both countries. About 75–85% of Canadian trade is with the United States, and Canada is the United States' largest trading partner and chief supplier of oil. While there are disputed issues between the two nations, relations are close and the two countries share the "world's longest undefended border". A high volume of trade and migration between the United States and Canada since the 1850s has generated closer ties, despite continued Canadian fears of being culturally overwhelmed by its neighbor, which is nine times larger in terms of population and eleven times larger in terms of economy. The two economies have increasingly merged since the North American Free Trade Agreement (NAFTA) of 1994, which also includes Mexico. This economic merger of these two countries was shifted when the Trump era United States–Mexico–Canada Agreement (USMCA) was ratified. |
| Chile | 1824 | See Chile–United States relationsRelations between Chile and the United States have been better in the period 1988 to 2008 than any other time in history. In the late 1980s and early 1990s, the United States government applauded the rebirth of democratic practices in Chile, Regarded as one of the least corrupt and most vibrant democracies in South America, with a healthy economy, Chile is noted as being a valuable ally of the United States in the Southern Hemisphere. A prime example of cooperation includes the landmark 2003 Chile–United States Free Trade Agreement. |
| Colombia | 1822 | See Colombia–United States relationsRelations between Colombia and the United States have evolved from mutual cordiality during most of the 19th and early 20th centuries to a recent partnership that links the governments of both nations around several key issues, including fighting communism, the War on Drugs, and especially since 9/11, the threat of terrorism. During the last fifty years, different American governments and their representatives have become involved in Colombian affairs through the implementation of policies concerned with the above issues. Some critics of current United States policies in Colombia, such as Law Professor John Barry, consider that US influences have catalyzed internal conflicts and substantially expanded the scope and nature of human rights abuses in Colombia. Supporters, such as Under Secretary of State Marc Grossman, consider that the US has promoted respect for human rights and the rule of law in Colombia, in addition to the fight against drugs and terrorism. |

| Ecuador | 1832 | See Ecuador–United States relations |
| El Salvador | 1824; 1849 | See El Salvador–United States relations |
| Guatemala | 1824; 1844 | See Guatemala–United States relations |
| Guyana | 1966 | See Guyana–United States relations |
| Honduras | 1824; 1853 | See Honduras–United States relationsHonduras and the United States have had formal relations since 1830. There is close cooperation between the two countries, particularly in the areas of the War on Drugs, while the National Port Authority in Puerto Cortés is part of the U.S. Bureau of Customs and Border Protection's Container Security Initiative. |
| Mexico | 1822 | See Mexico–United States relationsThe United States shares a unique and often complex relationship with the United Mexican States. A history of armed conflict goes back to the Texas Revolution in the 1830s, the Mexican–American War in the 1840s, and an American invasion in the 1910s. Important treaties include the Gadsden Purchase, and multilaterally with Canada, the North American Free Trade Agreement which was changed in the Trump era to the United States–Mexico–Canada Agreement. The two countries have close economic ties, being each other's first and third largest trading partners. They are also closely connected demographically, with over one million U.S. citizens living in Mexico and Mexico being the largest source of immigrants to the United States. Illegal immigration and illegal trade in drugs and firearms have been causes of differences but also of cooperation. |
| Nicaragua | 1824; 1849 | See Nicaragua–United States relationsNicaragua and the United States have had diplomatic relations since 1824. Between 1912 and 1933, the United States occupied Nicaragua (see United States occupation of Nicaragua). Following the United States occupation of Nicaragua, in 1933 the Somoza family political dynasty came to power, and would rule Nicaragua until their ouster on July 19, 1979, during the Nicaraguan Revolution. The era of Somoza family rule was characterized by rising inequality and political corruption, strong U.S. support for the government and its military, as well as a reliance on U.S.-based multinational corporations. This led to international condemnation of the regime, and in 1977 the Carter administration cut off aid to the Somoza regime due to its human rights violations.Then during the Reagan administration the diplomatic relations escalated during the Iran-Contra affair and the United States embargo against Nicaragua. Then in 1990, after Violeta Chamorro won the 1990 Nicaraguan general election, the diplomatic relations began to improve greatly. The United States has promoted national reconciliation, encouraging Nicaraguans to resolve their problems through dialogue and compromise. In the Summer 2003 Nicaragua sent around 370 soldiers to the Iraq War as part of the coalition of countries that were engaging in war in this country. Immediately after April 2004 these troops were withdrawn by President Enrique Bolanos. Although President Daniel Ortega has been publicly critical of U.S. policies, the United States and Nicaragua have normal diplomatic relations. |
| Panama | 1903 | See Panama–United States relationsPanama gained its independence in 1901 due in part to American interest in building the Panama Canal. Relations have been generally strong, with 25,000 U.S. citizens present in Panama and a mutual healthcare program. The United States invaded Panama in 1989 to remove then Panamanian leader Manual Noriega. |
| Paraguay | 1852 | See Paraguay–United States relations |
| Peru | 1826 | See Peru–United States relations |
| Suriname | 1975 | See Suriname–United States relations |
| Uruguay | 1836 | See Uruguay - United States relationsIn 2002, Uruguay and the United States created a Joint Commission on Trade and Investment (JCTI) to exchange ideas on a variety of economic topics. In March 2003, the JCTI identified six areas of concentration until the eventual signing of the Free Trade Area of the Americas (FTAA): customs issues, intellectual property protection, investment, labor, environment, and trade in goods. In late 2004, Uruguay and the United States signed an Open Skies Agreement, which was ratified in May 2006. In November 2005, they signed a Bilateral investment treaty (BIT), which entered into force on November 1, 2006. A Trade and Investment Framework Agreement (TIFA) was signed in January 2007. More than 80 US-owned companies operate in Uruguay, and many more market US goods and services. |
| Venezuela | 1835 | See Venezuela-United States relations and Venezuelan presidential crisisBoth countries maintained mutual diplomatic relationships since the early-19th century traditionally been characterized by an important trade and investment relationship and cooperation in controlling the production and transit of illegal drugs. Relations were strong under democratic governments in Venezuela, such as those of Carlos Andrés Pérez and Rafael Caldera. After the election of Presidents Hugo Chávez of Venezuela and George W. Bush of the United States, tensions between the countries escalated, reaching a high in September 2008 when Venezuela broke off diplomatic relations with the United States. In January 2019, after US President Donald Trump recognized Juan Guaidó as the Interim President of Venezuela, President Nicolás Maduro cut all diplomatic ties to the United States. |

### Europe

American relations with Eastern Europe are influenced by the legacy of the Cold War. Since the collapse of the Soviet Union, former Communist-bloc states in Europe have gradually transitioned to democracy and capitalism. Many have also joined the European Union and NATO, strengthening economic ties with the broader Western world and gaining the military protection of the United States via the North Atlantic Treaty.

In early March 2009, Obama proclaimed that US sanctions would be protracted provisionally for another year, because Zimbabwe's political crisis is as yet unresolved. |

### Asia
#### West Asia and Middle East

The United States has many important allies in the Greater Middle East region. These allies are Turkey, Saudi Arabia, Morocco, Jordan, Afghanistan (formerly), Israel, Egypt, Kuwait, Bahrain and Qatar. Israel and Egypt are leading recipients of United States foreign aid, receiving $2.775 billion and 1.75 billion in 2010. Turkey is an ally of the United States through its membership in NATO, while all of the other countries except Saudi Arabia and Qatar are major non-NATO allies.
The United States toppled the government of Saddam Hussein during the 2003 invasion of Iraq. Turkey is host to approximately 90 B61 nuclear bombs at Incirlik Air Base. Other allies include Qatar, where 3,500 US troops are based, and Bahrain, where the United States Navy maintains NSA Bahrain, home of NAVCENT and the Fifth Fleet.

| United Arab Emirates | 1972 | See United Arab Emirates–United States relations The United States was the third country to establish formal diplomatic relations with the UAE and has had an ambassador resident in the UAE since 1974. The two countries have enjoyed friendly relations with each other and have developed into friendly government-to-government ties which include security assistance. UAE and US had enjoyed private commercial ties, especially in petroleum. The quality of UAE–US relations increased dramatically as a result of the US-led coalition's campaign to end the Iraqi occupation of Kuwait. UAE ports host more US Navy ships than any port outside the US. |
| Yemen | 1946 | See United States–Yemen relations Traditionally, United States – Yemen relations have been tepid, as the lack of strong military-to-military ties, commercial relations, and support of Yemeni President Ali Abdullah Saleh has hindered the development of strong bilateral ties. During the early years of the George W. Bush administration, relations improved under the rubric of the War on Terror, though Yemen's lack of policies toward wanted terrorists has stalled additional US support. |

The United States and Turkmenistan continue to disagree about the country's path toward democratic and economic reform. The United States has publicly advocated industrial privatization, market liberalization, and fiscal reform, as well as legal and regulatory reforms to open up the economy to foreign trade and investment, as the best way to achieve prosperity and true independence and sovereignty. |
| Uzbekistan | 1991 | See United States–Uzbekistan relations Relations improved slightly in the latter half of 2007, but the U.S.A. continues to call for Uzbekistan to meet all of its commitments under the March 2002 Declaration of Strategic Partnership between the two countries. The declaration covers not only security and economic relations but political reform, economic reform, and human rights. Uzbekistan has Central Asia's largest population and is vital to US, regional, and international efforts to promote stability and security. |

#### South Asia

| Country | Formal relations began | Notes |
| Afghanistan | 1935 | See Afghanistan–United States relations In 2021, the Taliban overthrew the U.S.-backed Islamic Republic of Afghanistan concurrent with the withdrawal of U.S. troops, leading to the relocation of the U.S. Embassy in Kabul to Doha, Qatar. On November 12, 2021, the U.S. announced that an interests section would open at the Embassy of Qatar in Kabul on December 31, to serve as the protecting power for the U.S. in Afghanistan. The Islamic Republic's diplomatic missions to the U.S. operated independently for several months before shutting down operations and transferring custody of the properties to the U.S. State Department on March 16, 2022. Afghanistan has no protecting power in the U.S. |
| Bangladesh | 1972 | See Bangladesh–United States relations Today the relationship between the two countries is based on what is described by American diplomats as the "three Ds", meaning Democracy, Development and Denial of space for terrorism. The United States is closely working with Bangladesh in combating Islamic extremism and terrorism and is providing hundreds of millions of dollars every year in economic assistance. |
| Bhutan | Does not have formal, only informal relations | See Bhutan–United States relations While the United States has no formal diplomatic relations with Bhutan, it maintains informal contact through its embassy in New Delhi, India. The US has offered to resettle 60,000 of the 107,000 Bhutanese refugees of Nepalese origin now living in seven UN refugee camps in southeastern Nepal. |
| India | 1947 | See India–United States relations The relationships between India in the days of the British Raj and the US were thin. Swami Vivekananda promoted Yoga and Vedanta in America at the World's Parliament of Religions in Chicago, during the World's Fair in 1893. Mark Twain visited India in 1896 and described it in his travelogue Following the Equator with both revulsion and attraction before concluding that India was the only foreign land he dreamed about or longed to see again. Regarding India, Americans learned more from English writer Rudyard Kipling. Mahatma Gandhi had an important influence on the philosophy of non-violence promoted by Martin Luther King Jr. in the 1950s. At present, India and the US share an extensive and expanding cultural, strategic, military, and economic relationship which is in the phase of implementing confidence building measures (CBM) to overcome the legacy of trust deficit – brought about by adversarial US foreign policies and multiple instances of technology denial – which have plagued the relationship over several decades. Unrealistic expectations after the conclusion of the 2008 India–United States Civil Nuclear Agreement (which underestimated negative public opinion regarding the long-term viability of nuclear power generation and civil-society endorsement for contractual guarantees on safeguards and liability) has given way to pragmatic realism and refocus on areas of cooperation which enjoy favourable political and electoral consensus. |

#### East Asia

| Country | Formal relations began | Notes |
| People's Republic of China | 1844 (Qing) 1979 (PRC) | See China–United States relations and East Asia island arcs The United States and the People's Republic of China have extensive yet complex economic relationships and partnerships. A great amount of trade between the two countries necessitates positive economic relations, although occasional disagreements over tariffs, currency exchange rates, intellectual property theft, and the political status of Taiwan occurs. The United States has criticized China on such human rights issues as the 1989 Tiananmen Square protests, the persecution of Falun Gong, and more recently the mass detaining of Uyghurs, Kazakhs, and other ethnic and religious minorities in Xinjiang, as well the forced sinicization of Mongols and Tibetans. China has criticized the United States on human rights issues in response and accused the latter of "interfering in China's internal affairs". The United States acknowledges the PRC's One-China policy. The relations deteriorated sharply under Chinese Communist Party general secretary Xi Jinping, with issues such as China's militarization of the South China Sea and Chinese espionage in the United States arising. U.S. president Donald Trump launched a trade war against China, banned U.S. companies from selling equipment to Huawei, increased visa restrictions on Chinese students and scholars, and designated China as a "currency manipulator". The more confrontational policy has endured during the Biden administration, which focuses on China's treatment of Hong Kong, the threats against Taiwan, the persecution of Uyghurs in China, and Chinese cyberwarfare. In response, China has adopted "wolf warrior diplomacy" to counter allegations they see as incorrect and damaging to the American-Chinese dialogue. |
| Republic of China (Taiwan) | 1844 (Qing) 1911 (ended in 1979) 1979 (Taiwan Relations Act - unofficial) 2018 (Taiwan Travel Act) - high-level working partnership | See Taiwan–United States relations The United States recognized the Nationalist Government as the legitimate government of all of China throughout the Chinese Civil War. The U.S. continued to recognize the Republic of China until 1979, when it shifted its recognition to the People's Republic of China in accordance with the One China policy, where the U.S. 'acknowledge', or take note of, the Chinese position on Taiwan but not 'recognizing' or accepting it, which allows the U.S. flexibility to pursue unofficial but robust relations with Taipei. The U.S. continued to provide Taiwan with military aid after 1979, and continued informal relations through the American Institute in Taiwan, and Taiwan is considered to be a strong Asian ally and supporter of the United States. The U.S. Congress passed the Taiwan Travel Act on February 28, 2018, and the bill was subsequently signed into federal law by President Donald Trump, formalizing high-level communications between Washington and Taipei as well as permitting intergovernmental contact at the highest level. |
| Hong Kong | 1992 | See Hong Kong–United States relations U.S. foreign policy toward Hong Kong, grounded in a determination to promote Hong Kong's prosperity, autonomy, and way of life, is stated in the U.S.–Hong Kong Policy Act of 1992. It rules that the U.S. would continue to treat Hong Kong apart from the People's Republic of China even after the 1997 transfer of sovereignty marking the end of British rule. The United States maintains substantial economic and political interests in Hong Kong. The United States supports Hong Kong's autonomy by concluding and implementing bilateral agreements; promoting trade and investment; arranging high-level visits; broadening law enforcement cooperation; bolstering educational, academic, and cultural links; and supporting the large community of U.S. citizens and visitors. |
| Macau | 1999 | See Macau–United States relations In recognition of Macau's high degree of autonomy, the United States continues to treat Macau as a "special area" distinct from the People's Republic of China. Macau's clothes and textiles continued to enter the United States under quotas separated from those of China. Under the terms of a September 2000 bilateral memorandum of understanding, Macau and the U.S. government cooperate in enforcing textile quotas and preventing illegal trans-shipment. The United States continued periodic visits by U.S. Customs Textile Production Verification Teams to ensure compliance with Macau bilateral textile commitments. |
| Japan | 1854, 1952 | See Japan–United States relations The relationship began in the 1850s, as the United States was a major factor in forcing Japan to resume contacts with the outer world beyond a very restricted role. In the late 19th century, the Japanese sent many delegations to Europe, and some to the U.S., to discover and copy the latest technology and thereby modernize Japan very rapidly and allow it to build its own empire. There was some friction over control of Hawaii and the Philippines, but Japan stood aside as the U.S. annexed those lands in 1898. Likewise, the U.S. did not object when Japan took control of Korea. The two nations cooperated with the European powers in suppressing the Boxer Rebellion in China in 1900, but the U.S. was increasingly troubled about Japan's denial of the Open Door Policy that would ensure that all nations could do business with China on an equal basis. President Theodore Roosevelt admired Japan's strength as it defeated a major European power, Russia. He brokered an end to the war between Russia and Japan in 1905–6. Anti-Japanese sentiment (especially on the West Coast) soured relations in the 1907–24 era. In the 1930s, the U.S. protested vehemently against Japan's seizure of Manchuria (1931), its war against China (1937–45), and its seizure of Indochina (Vietnam) 1940–41. American sympathies were with China and Japan rejected increasingly angry American demands that Japan pull out of China. The two nations fought an all-out war 1941–45; the U.S. won a total victory, with heavy bombing (including two atomic bombs on Hiroshima and Nagasaki) that devastated Japan's 50 largest industrial cities. The U.S. Army under Douglas MacArthur occupied and ruled Japan, 1945–51, with the successful goal of sponsoring a peaceful, prosperous and democratic nation. In 1951, the United States and Japan signed Treaty of San Francisco and Security Treaty Between the United States and Japan, subsequently revised as Treaty of Mutual Cooperation and Security between the United States and Japan in 1960, relations since then have been excellent. The United States considers Japan to be one of its closest allies, and it is both a major non-NATO ally and NATO contact country. The United States has several military bases in Japan including Yokosuka, which harbors the US 7th Fleet. The JSDF, or Japanese Self Defense Force, cross-train with the U.S. military, often providing auxiliary security and conducting war games. |

| South Korea | 1882 (Joseon); 1949 (Republic) | See South Korea–United States relations South Korea–United States relations have been most extensive since 1945, when the United States helped establish capitalism in South Korea and led the UN-sponsored Korean War against North Korea and China (1950–53). South Korea's rapid economic growth, democratization and modernization greatly reduced its U.S. dependency. Large numbers of U.S. forces remain in South Korea. On September 24, 2018, U.S. president Donald Trump signed a renegotiated trade agreement with South Korean President Moon Jae-in. |

#### Southeast Asia

Many countries in the Association of Southeast Asian Nations (ASEAN) are important partners for United States in both economic and geostrategic aspects. ASEAN's geostrategic importance stems from many factors, including: the strategic location of member countries, the large shares of global trade that pass through regional waters, and the alliances and partnerships which the United States shares with ASEAN member states. In July 2009, the United States signed ASEAN's Treaty of Amity and Cooperation, which establishes guiding principles intended to build confidence among its signatories with the aim of maintaining regional peace and stability. Trade flows are robust and increasing between America and the ASEAN region.

| Brunei | 1984 | See Brunei–United States relations The United States welcomed Brunei Darussalam's full independence from the United Kingdom on January 1, 1984, and opened an embassy in Bandar Seri Begawan on that date. Brunei opened its embassy in Washington, D.C. in March 1984. Brunei's armed forces engage in joint exercises, training programs, and other military cooperation with the US. A memorandum of understanding on defense cooperation was signed on November 29, 1994. The Sultan of Brunei visited Washington in December 2002. |
| Cambodia | 1950 | See Cambodia–United States relations |
| Indonesia | 1949 | See Indonesia–United States relations As the largest ASEAN member, Indonesia has played an active and prominent role in developing the organization. For United States, Indonesia is important for dealing with certain issues; such as terrorism, democracy, and how United States project its relations with Islamic world, since Indonesia has the world's largest Islamic population, and one that honors and respects religious diversity. The United States views Indonesia as a potential strategic ally in Southeast Asia. During his stately visit to Indonesia, US president Barack Obama has held up Indonesia as an example of how a developing nation can embrace democracy and diversity. |
| Laos | 1950 | See Laos–United States relations |
| Malaysia | 1957 | See Malaysia–United States relations Despite increasingly strained relations under the Mahathir Mohamad government, ties have been thawed under Najib Razak's administration. Economic ties are particularly robust, with the United States being Malaysia's largest trading partner and Malaysia is the tenth-largest trading partner of the US. Annual bilateral trade amounts to $50 billion. The United States and Malaysia launched negotiations for a bilateral free trade agreement (FTA) in June 2006. The United States and Malaysia enjoy strong security cooperation. Malaysia hosts the Southeast Asia Regional Center for Counterterrorism (SEARCCT), where over 2000 officials from various countries have received training. The United States is among the foreign countries that has collaborated with the center in conducting capacity building programmes. The United States and Malaysia share a strong military-to-military relationship with numerous exchanges, training, joint exercises, and visits. |
| Myanmar | 1948 | See Myanmar–United States relations Bilateral ties have generally been strained but are slowly improving. The United States has placed broad sanctions on Burma because of the military crackdown in 1988 and the military regime's refusal to honour the election results of the 1990 People's Assembly election. Similarly, the European Union has placed embargoes on Burma, including an arms embargo, cessation of trade preferences, and suspension of all aid with the exception of humanitarian aid. US and European government sanctions against the military government, alongside boycotts and other types direct pressure on corporations by western supporters of the Burmese democracy movement, have resulted in the withdrawal from Burma of most United States and many European companies. However, several Western companies remain due to loopholes in the sanctions. Asian corporations have generally remained willing to continue investing in Myanmar and to initiate new investments, particularly in natural resource extraction. Ongoing reforms have improved relations between Burma and the United States. However the Rohingya Crisis has been deteriorating ties. |
| Philippines | 1946 | See Philippines–United States relations The Philippines and the United States have an extremely strong relationship with each other due to their long-standing alliance. The Philippine-USA links stretch back in time. The first Asians in the Americas were the Filipinos. The first recorded advent of Filipinos in what is now the United States date to October 1587 around Morro Bay, California, with the first permanent settlement in Louisiana in 1763, they were named "Manilamen" and they served in the Battle of New Orleans during the closing stages of the War of 1812, when the British Empire and American Republic once again went to war against each other as Filipinos in Saint Malo supported the American side against the British Empire. One American state, due to it being a former Spanish territory, Texas, was even once called "The New Philippines", so named since the Spanish wanted to replicate the prosperity they achieved in the Philippines, in that territory in the Americas. The Spanish government ceded the Philippines to the United States in the 1898 Treaty of Paris that ended the Spanish–American War and led to the Philippine–American War. The Philippines was a United States colony from 1898 to 1946. The United States finally recognized Philippine independence on July 4, 1946, in the Treaty of Manila. July 4 was observed in the Philippines as Independence Day until August 4, 1964, when, upon the advice of historians and the urging of nationalists, President Diosdado Macapagal signed into law Republic Act No. 4166 designating June 12 as the country's Independence Day. The United States and the Philippines have fought together in many conflicts such as World War I, World War II, the Korean War, Vietnam War, Islamic insurgency in the Philippines, Gulf War and the War on Terror. The Philippines and the United States still maintain close, friendly, diplomatic, political and military relations with more than 100,000 US citizens and nationals living in the Philippines and more than 4 million Filipinos living in the United States. Both countries actively cooperate in the trade, investment and financial sectors. The US is also the largest investor in the Philippine economy with an estimated total worth of $63 billion. The United States and the Philippines conduct joint military exercises called the Balikatan that take place once a year to boost relations between the two countries. The US military also conducts humanitarian and aid missions in the Philippines. The Philippines is one out of two major US allies in South East Asia. Since 2003 the US has designated the Philippines as a major non-NATO ally. However, relations between the United States and the Philippines began to deteriorate in 2016 with Philippines president Rodrigo Duterte wanting to form an alliance with China and Russia and separating the country from all connections and ties with the United States, both economically and socially. |

As diplomatic ties between the nations grew, the United States opened a consulate general in Ho Chi Minh City, and Vietnam opened a consulate in San Francisco. Today, the United States views Vietnam as a potential strategic ally in Southeast Asia. |

### Oceania

| Country | Formal relations began | Notes |
| Australia | 1940 | See Australia–United States relations Australia and the United States have long been close and strategic allies and have traditionally been aligned with the Commonwealth of Nations. The two countries have a shared history, both have previously been British Colonies and many Americans flocked to the Australian goldfields in the 19th century. At the strategic level, the relationship really came to prominence in the Second World War, when the two nations worked extremely closely in the Pacific War against Japan, with General Douglas MacArthur undertaking his role as Supreme Allied Commander based in Australia, effectively having Australian troops and resources under his command. During this period, the cultural interaction between Australia and the United States were elevated to a higher level as over 1 million US military personnel moved through Australia during the course of the war. The relationship continued to evolve throughout the second half of the 20th century, and today now involves strong relationships at the executive and mid levels of government and the military, leading Assistant Secretary of State for East Asian and Pacific Affairs, Kurt M. Campbell to declare that "in the last ten years, [Australia] has ascended to one of the closest one or two allies [of the US] on the planet". It was also strengthened its relationship with the United States as Britain's influence in Asia declined. At the governmental level, United States-Australia relations are formalized by the ANZUS treaty and the Australia–United States Free Trade Agreement. |
| Cook Islands | 1995 | See Cook Islands–United States relations The Cook Islands are an Associated State of New Zealand and has consular relations with the United States, in addition as early as 1980, the two sides signed the Cook Islands-United States Maritime Boundary Treaty. On September 25, 2023, the two sides established diplomatic relations. |
| Fiji | 1971 | See Fiji–United States relations Relations are currently steady since Fiji's elections in September 2014. The United States had opposed Fiji's unelected government, which came to power through a military coup in December 2006. The United States suspended $2.5 million in aid money pending a review of the situation, following the 2006 coup. |
| Kiribati | 1980 | See Kiribati–United States relations Relations between Kiribati and the United States are excellent. Kiribati signed a treaty of friendship with the United States after independence in 1979. The United States has no consular or diplomatic facilities in the country. Officers of the American Embassy in Suva, Fiji, are concurrently accredited to Kiribati and make periodic visits. The US Peace Corps maintained a program in Kiribati from 1974 to 2008. |
| Marshall Islands | 1986 | See Marshall Islands–United States relations The Marshall Islands is a sovereign nation in "free association" with the United States. The Marshall Islands and the United States maintain excellent relations. After more than a decade of negotiation, the Marshall Islands and the United States signed the Compact of Free Association on June 25, 1983. The Compact gives the US full authority and responsibility over defense of the Marshall Islands. The Marshall Islands and the United States both lay claim to Wake Island. The Compact that binds the Marshall Islands and the United States is the same one that binds the United States and the Federated States of Micronesia and Palau. |
| Federated States of Micronesia | 1986 | See Federated States of Micronesia–United States relations Reflecting a strong legacy of Trusteeship cooperation, over 25 US federal agencies continue to maintain programs in the FSM. The United States and the FSM share very strong relations. Under the Amended Compact, the US has full authority and responsibility for the defense of the FSM.

| Nauru | 1976 | See Nauru–United States relations Relations between Nauru and the United States are complicated.

| New Zealand | 1942 | See New Zealand–United States relations United States-New Zealand relations are strong, but complex. The United States has historically assisted New Zealand in times of turmoil; for instance, during World War II, US bombing Hiroshima and Nagasaki, and with the September 2010 Canterbury earthquake and the February 2011 Christchurch earthquake. New Zealand has reciprocated; for example, by participating in the Korean War and the Vietnam War. However, the United States suspended its mutual defense obligations to New Zealand because of the state's non-nuclear policies. In 1996, the United States under President Bill Clinton reinstated New Zealand's status from a 'friend' to an 'ally' by designating New Zealand as a major non-NATO ally. Despite disagreements between the two countries, the bilateral trade, security, and cultural relationship continued to flourish. New Zealand continued to play a supportive role in international conflicts in Somalia, Bosnia, and the Persian Gulf. New Zealand and the United States are close collaborators in the international intelligence alliance, Five Eyes, which is one of the most comprehensive known espionage alliances in history. Following the 9/11 attacks on the United States in 2001, New Zealand supported international counter-terrorism efforts and assisted the United States throughout the war in Afghanistan. Throughout the 2000s, the United States has remained New Zealand's fourth-largest trading partner and third-largest source of visitors. |

Niue is in free association with New Zealand. On internal matters it is self-governing. Niue conducts its foreign affairs in conjunction with New Zealand. Niue has declared and does manage its exclusive economic zone. The United States requested, and received, confirmation from New Zealand that the Government of Niue had the competence to enter into this agreement with the United States." On September 25, 2023, the two sides established diplomatic relations. |
| Palau | 1996 | See Palau–United States relations On October 1, 1994, after five decades of US administration, the country of Palau became the last component of the Trust Territory of the Pacific Islands to gain its independence. In 1978, Palau decided not to join the Federated States of Micronesia, due to culture and language differences, and instead sought independence. In 1986, the Compact of Free Association agreement between Palau and the United States was approved, paving the way for Palau's independence. |
