# Foreign relations of Iran

"none" is preferred when the title is sufficiently descriptive; see [[WP:SDNONE]]
Geography is an important factor in informing Iran's foreign policy. Following the 1979 Iranian Revolution, the newly formed Islamic Republic, under the leadership of Ayatollah Khomeini, dramatically reversed the pro-American foreign policy of the last Shah of Iran Mohammad Reza Pahlavi. Since the country's policies then oscillated between the two opposing tendencies of revolutionary ardour to eliminate non-Muslim Western influences while promoting the Islamic revolution abroad, and pragmatism, which would advance economic development and normalization of relations, bilateral dealings can be confused and contradictory.
According to data published by the Reputation Institute, Iran is the world's second least internationally reputable country, just ahead of Iraq, and has held that position for the three consecutive years of 2016, 2017, and 2018. Islamism and nuclear proliferation are recurring issues with Iran's foreign relations. In a series of international polls by Pew Research in 2012, only one country (Pakistan) had the majority of its population supporting Iran's right to acquire nuclear arms; every other population polled overwhelmingly rejected a nuclear-armed Iran (90–95% opposed in the polled European, North American, and South American countries), and majorities in most of them were in favor of military action to prevent a nuclear-armed Iran from materializing. Additionally, the majority of Americans, Brazilians, Japanese, Mexicans, Egyptians, Germans, Britons, French, Italians, Spaniards, and Poles (among other national groups) had majority support for "tougher sanctions" on Iran, while majorities in China, Russia, and Turkey opposed tougher sanctions.

## Background

Iranians have traditionally been highly sensitive to foreign interference in their country, pointing to such events as the Russian conquest of northern parts of the country in the course of the 19th century, the tobacco concession, the British and Russian occupations of the First and Second World Wars, and the CIA plot to overthrow Prime Minister Mohammed Mosaddeq. This suspicion manifests itself in attitudes that many foreigners might find incomprehensible, such as the "fairly common" belief that the Iranian Revolution was actually the work of a conspiracy between Iran's Shi'a clergy and the British government. This may have been a result of the anti-Shah bias in BBC Radio's influential Persian broadcasts into Iran: a BBC report of 23 March 2009 explains that many in Iran saw the broadcaster and the government as one, and interpreted the bias for Khomeini as evidence of weakening British government support for the Shah. It is entirely plausible that the BBC did indeed help hasten revolutionary events.

## Revolutionary period under Khomeini

Under Khomeini's government, Iran's foreign policy often emphasized the elimination of foreign influence and the spread of Islamic revolution over state-to-state relations or the furtherance of trade. In Khomeini's own words:
   We shall export our revolution to the whole world. Until the cry "There is no God but Allah" resounds over the whole world, there will be struggle.
The Islamic Republic's effort to spread the revolution is considered to have begun in earnest in March 1982, when 380 men from more than 25 Arab and Islamic nations met at the former Tehran Hilton Hotel for a "seminar" on the "ideal Islamic government" and, less academically, the launch of a large-scale offensive to cleanse the Islamic world of the satanic Western and Communist influences that were seen to be hindering the Islamic world's progress. The gathering of militants, primarily Shi'a but including some Sunnis, "with various religious and revolutionary credentials", was hosted by the Association of Militant Clerics and the Pasdaran Islamic Revolutionary Guards. The nerve centre of the revolutionary crusade, operational since shortly after the 1979 revolution, was located in downtown Tehran and known to outsiders as the "Taleghani Centre". Here the groundwork for the gathering was prepared: the establishment of Arab cadres, recruited or imported from surrounding countries to spread the revolution, and provision of headquarters for such groups as the Islamic Front for the Liberation of Bahrain, the Iraqi Shi'a movement, and Philippine Moro, Kuwaiti, Saudi, North African and Lebanese militant clerics.
These groups came under the umbrella of the "Council for the Islamic Revolution", which was supervised by Ayatollah Hussein Ali Montazeri, the designated heir of Ayatollah Khomeini. Most of the council's members were clerics, but they also reportedly included advisors from the Syrian and Libyan intelligence agencies. The council apparently received more than $1 billion annually in contributions from the faithful in other countries and in funds allocated by the Iranian government.
Its strategy was two-pronged: armed struggle against what were perceived as Western imperialism and its agents; and an internal purifying process to free Islamic territory and Muslim minds of non-Islamic cultural, intellectual and spiritual influences, by providing justice, services, resources to the mustazafin (weak) masses of the Muslim world. These attempts to spread its Islamic revolution strained the country's relations with many of its Arab neighbours, and the extrajudicial execution of Iranian dissidents in Europe unnerved European nations, particularly France and Germany. For example, the Islamic Republic expressed its opinion of Egypt's secular government by naming a street in Tehran after Egyptian President Anwar Sadat's killer, Khalid al-Istanbuli. At this time Iran found itself very isolated, but this was a secondary consideration to the spread of revolutionary ideals across the Persian Gulf and confrontation with the US (or "Great Satan") in the 1979-1981 hostage crisis.

### Training volunteers

Arab and other Muslim volunteers who came to Iran were trained in camps run by the Revolutionary Guards. There were three primary bases in Tehran, and others in Ahvaz, Isfahan, Qom, Shiraz, and Mashhad, and a further facility, converted in 1984, near the southern naval base at Bushire.
In 1981 Iran supported an attempt to overthrow the Bahraini government, in 1983 expressed political support for Shi'ites who bombed Western embassies in Kuwait, and in 1987 Iranian pilgrims rioted at poor living conditions and treatment during the Hajj (pilgrimage) in Mecca, Saudi Arabia, and were consequently massacred. Nations with strong fundamentalist movements, such as Egypt and Algeria, also began to mistrust Iran. With the Israeli invasion of Lebanon, Iran was thought to be supporting the creation of the Hizballah organization. Furthermore, Iran went on to oppose the Arab–Israeli peace process, because it saw Israel as an illegal country.

### Iran–Iraq War

Iranian relations with Iraq have never been good. They took a turn for the worse in 1980 when Iraq invaded Iran. The stated reason for Iraq's invasion was the contested sovereignty over the Shatt al-Arab waterway (Arvand Rud in Persian). Other unstated reasons were probably more significant: Iran and Iraq had a history of interference in each other's affairs by supporting separatist movements, although this interference had ceased since the Algiers Agreement.
Iran demanded the withdrawal of Iraqi troops from Iranian territory and the return to the status quo ante for the Shatt al-Arab, as established under the Algiers Agreement. This period saw Iran become even more isolated, with virtually no allies. Exhausted by the war, Iran signed UN Security Council Resolution 598 in July 1988, after the United States and Germany began supplying Iraq with chemical weapons. The ceasefire resulting from the UN resolution was implemented on 20 August 1988. Neither nation had made any real gains in the war, which left one million dead and had a dramatic effect on the country's foreign policy. From this point on, the Islamic Republic recognized that it had no choice but to moderate its radical approach and rationalize its objectives. This was the beginning of what Anoushiravan Ehteshami calls the "reorientation phase" of Iranian foreign policy.

### Pragmatism

Like other revolutionary states, practical considerations have sometimes led the Islamic Republic to inconsistency and subordination of such ideological concerns as pan-Islamic solidarity. One observer, Graham Fuller, has called the Islamic Republic "stunningly silent"
   about [Muslim] Chechens in [non-Muslim] Russia, or Uyghurs in China, simply because the Iranian state has important strategic ties with both China and Russia that need to be preserved in the state interest. Iran has astonishingly even supported Christian Armenia in the First Nagorno-Karabakh War against Shi'ite Azerbaijan and has been careful not to lend too much support to Islamic Tajiks in Tajikistan, where the language is basically a dialect of Persian.
In this regard the Islamic Republic resembles another revolutionary state, the old Soviet Union. The USSR was ideologically committed not to Islam but to world proletarian revolution, led by Communist parties under its leadership, but "frequently abandoned support to foreign communist parties when it served Soviet national interests to cooperate with the governments that were oppressing them."

### Post-War period (1988–present)

Since the end of the Iran–Iraq War, Iran's new foreign policy has had a dramatic effect on its global standing. Relations with the European Union have dramatically improved, to the point where Iran is a major oil exporter and a trading partner with such countries as Italy, France, and Germany. China and India have also emerged as friends of Iran; these three countries face similar challenges in the global economy as they industrialize, and consequently find themselves aligned on a number of issues.
Iran maintains regular diplomatic and commercial relations with Russia and the former Soviet Republics. Both Iran and Russia believe they have important national interests at stake in developments in Central Asia and the Transcaucasus, particularly concerning energy resources from the Caspian Sea.

### Significant historical treaties

* Treaty of Zuhab by which Iran irrevocably lost Mesopotamia (Iraq) to the Ottomans. Roughly settled the modern-day Iran-Iraq-Turkey borders
* Treaty of Gulistan 1813, by which Iran irrevocably lost Georgia, Dagestan, and most of Azerbaijan.
* Treaty of Turkmenchay 1828, by which Iran irrevocably lost Armenia and the remainder of the contemporary Republic of Azerbaijan (comprising the Lankaran and Nakchivan khanates.
* Treaty of Akhal
* Treaty of Paris (1857) (by which Iran renounced claims over Herat and parts of Afghanistan)
* Anglo-Russian Convention of 1907

## Current policies

The Islamic Republic of Iran accords priority to its relations with the other states in the region and with the rest of the Islamic world. This includes a strong commitment to the Organisation of Islamic Cooperation (OIC) and the Non-Aligned Movement. Relations with the states of the Gulf Cooperation Council (GCC), especially with Saudi Arabia, are characterized by rivalry and hostility. An unresolved territorial dispute with the United Arab Emirates concerning three islands in the Persian Gulf continues to mar its relations with these states. Iran has close relations with Kuwait.
Iran seeks new allies around the world due to its increasing political and economic isolation in the international community. This isolation is evident in the various economic sanctions and the EU oil embargo that have been implemented in response to questions that have been raised over the Iranian nuclear program.
Tehran supports the Interim Governing Council in Iraq, but it strongly advocates a prompt and full transfer of state authority to the Iraqi people. Iran hopes for stabilization in Afghanistan and supports the reconstruction effort so that the Afghan refugees in Iran (which number approximately 2.5 million.) can return to their homeland and the flow of drugs from Afghanistan can be stemmed. Iran is also pursuing a policy of stabilization and cooperation with the countries of the Caucasus and Central Asia, whereby it is seeking to capitalise on its central location to establish itself as the political and economic hub of the region.
On the international scene, it has been argued by some that Iran has become, or will become in the near future, a superpower due to its ability to influence international events. Others, such as Robert Baer, have argued that Iran is already an energy superpower and is on its way to becoming an empire. Flynt Leverett calls Iran a rising power that might well become a nuclear power in coming years—if the US does not prevent Iran from acquiring nuclear technology, as part of a grand bargain under which Iran would cease its nuclear activities in exchange for a guarantee of its borders by the US.

### Territorial disputes

* Iran and Iraq restored diplomatic relations in 1990, but they are still trying to work out written agreements settling outstanding disputes from their eight-year war concerning border demarcation, prisoners of war, and freedom of navigation in and sovereignty over the Shatt al-Arab waterway.
* Iran governs and possesses two islands in the Persian Gulf claimed by the UAE: Lesser Tunb (which the UAE calls Tunb as Sughra in Arabic, and Iran calls Jazireh-ye Tonb-e Kuchek in Persian) and Greater Tunb (Arabic Tunb al Kubra, Persian Jazireh-ye Tonb-e Bozorg).
* Iran jointly administers with the UAE an island in the Persian Gulf claimed by the UAE (Arabic Abu Musa, Persian, Jazireh-ye Abu Musa), over which Iran has taken steps to exert unilateral control since 1992, including access restrictions.
* The Caspian Sea borders between Azerbaijan, Iran, and Turkmenistan are not yet determined, although this problem is set to be resolved peacefully in the coming years through slow negotiations. After the breakup of the USSR, the newly independent republics bordering the Caspian Sea claimed shares of territorial waters and the seabed, thus unilaterally abrogating the existing half-and-half USSR-Iran agreements which, like all other Soviet treaties, the republics had agreed to respect upon their independence. It has been suggested by these countries that the Caspian Sea should be divided in proportion to each bordering country's shoreline, in which case Iran's share would be reduced to about 13%. The Iranian side has expressed eagerness to know if this means that all Irano–Russian and –Soviet agreements are void, entitling Iran to claim territorial sovereignty over lands lost to Russia by treaties that the parties still consider vivant. Issues between Russia, Kazakhstan, and Azerbaijan were settled in 2003, but Iran does not recognize these agreements, on the premise that the international law governing open water can not be applied to the Caspian Sea, which is in fact a lake (a landlocked body of water). Iran has not pressed its Caspian territorial claims in recent years because it relies heavily on Russia's support in its nuclear-development battle with the West.

## Bilateral relations
### Africa

In 2009, Foreign Minister Manouchehr Mottaki said that if Iran and Africa works together, both can largely meet each other’s interest. Some signs of disillusionment began to emerge when 20 African nations threatened to close their embassies in Tehran following what they saw as Ahmadinejad's failure to live up to the promises he made during his trips to Africa. The Iranian government was not deterred by the misadventures, and some think it considers African countries strategically necessary to enable it to receive international support for its much criticized nuclear program.
| Country | Formal relations began | Notes |
| Algeria | | See Algeria–Iran relations Algeria is one of the few Arab and Sunni nations that has been friendly towards Iran. Iran is also one of the only states in the Middle East to voice support for the Polisario Front, a rebel movement backed by Algeria. Both countries also support the Syrian government of Bashar al-Assad. |
| Burundi | 31 March 1985 | See Burundi–Iran relations Both countries established diplomatic relations on 31 March 1985. |
| Comoros | | Comoros severed diplomatic relations with Iran in January 2016, but they were reestablished by 2023. |
| Egypt | 1939 (Diplomatic relations severed 30 April 1979) | See Egypt–Iran relations Egypt has an interest section in Tehran. |
| Gambia | | In November 2010, Gambia broke off diplomatic relations with Iran in reaction to a weapons shipment. The Gambian government allowed Iranians 48 hours to leave the country. Diplomatic relations were reestablished on 29 July 2024. |
| Ghana | | Iran and Ghana maintain a historic special relationship and Iran has an embassy in Ghana and Ghana has an embassy in Tehran. |
| Guinea-Bissau | 22 August 1990 | Both countries established diplomatic relations on 22 August 1990 Both countries cooperate in various fields (education, mining, health, pharmaceuticals, agriculture, development and energy). |
| Libya | 30 December 1967 | See Iran-Libya relations Both countries established diplomatic relations on 30 December 1967. The relations between two countries began in 1967 when both countries were governed by monarchs. The relations became strained when Muammar Gaddafi seized the power on 1 September 1969 due to his alliance with other Arab leaders such as Gamal Nasser against Shah Mohammad Reza. Libya broke ranks with most of the Arab states when it came out in support of Iran during the Iran–Iraq War. There is a Libyan embassy in Tehran and an Iranian embassy in Tripoli. |
| Morocco | (Diplomatic relations severed in May 2018) | See Iran–Morocco relations There have been several instances in which Iran and Morocco have mostly or completely severed diplomatic relations. Iran cut off diplomatic ties with Morocco in 1981 after King Hassan II gave asylum to the exiled Shah. It took almost a decade for relations to thaw; Prime Minister Abderrahmane Youssoufi of Morocco led the first Moroccan delegation to the Islamic Republic of Iran. Economic ties increased greatly in 2009. On 6 March 2009, Morocco severed diplomatic ties with Iran, offering several reasons. Morocco's Foreign Ministry said it was a result of Iran's spreading the Shi'ite variety of Islam in Sunni Morocco constituted interference in domestic affairs. On 1 May 2018, Morocco severed diplomatic ties with Iran over Tehran's support for the Polisario Front, a Western Sahara independence movement. Morocco Foreign Minister Nasser Bourita told reporters Morocco would close its embassy in Tehran and would expel the Iranian ambassador in Rabat. |
| Senegal | 13 May 1971 | See Iran–Senegal relations Both countries established diplomatic relations on 13 May 1971. Iranian president Mahmoud Ahmadinejad and his Senegalese counterpart Abdoulaye Wade pledged to expand bilateral ties in the fields of economics, tourism and politics in addition to increased efforts to empower OIC. Iran Khodro established an assembly line to produce Iranian cars in Senegal for African markets. The company had the capacity to produce 10,000 Samand cars annually. In February 2011, Senegal severed diplomatic relations with Iran as it accused Iran of supplying weapons to rebels in the Casamance region. |
| South Africa | 10 May 1994 | See Iran–South Africa relations Both countries established diplomatic relations on 10 May 1994. South Africa and Iran share historical bilateral relations and the latter supported the South African liberation movements. It severed official relations with South Africa in 1979 and imposed a trade boycott in protest against the country's Apartheid policies. In January 1994 Iran lifted all trade and economic sanctions against South Africa and diplomatic relations were reestablished on 10 May 1994. |
| Sudan | 22 August 1972 | See Iran–Sudan relations Both countries established diplomatic relations on 22 August 1972 Owing to various cultural and historical compatibilities, Iran and Sudan have generally sought a very cordial and friendly relationship. The two nations share membership in the OIC and the Group of 77. Although they differ in ethnic identity (Iran is predominantly Persian, while Sudan is Afro-Arab) and denomination (the two nations are Muslim, but the former is mainly Shi'a, while the latter is Sunni), Iran and Sudan have a common strategic bond with both the People's Republic of China and Russia, and a common animosity towards the United States. Relations between Tehran and Khartoum have continued to grow, especially since April 2006, when then President Mahmoud Ahmadinejad voiced his opposition to the deployment in the Darfur region of Western peacekeepers from the United Nations. Sudan ardently supports Iran's nuclear program. Both countries are also firmly against Israel. On 4 January 2016 Sudan cut off all diplomatic relations with Iran due to tensions between Saudi Arabia and Iran. On 6 July 2023, Iran and Sudan agreed to restore diplomatic relations. |
| Zimbabwe | 11 February 1983 | See Iran–Zimbabwe relations Both countries established diplomatic relations on 11 February 1983. There are growing economic, social and cultural ties between Iran and Zimbabwe.

A Canadian diplomatic mission was constructed in Tehran in 1959 and raised to Embassy status in 1961. Due to rocky relations after the Iranian Revolution, Iran did not establish an embassy in Canada until 1991 when its staff, which had been living in a building on Roosevelt Avenue in Ottawa's west end, moved into 245 Metcalfe Street in the Centretown neighbourhood of Ottawa and the mission was upgraded to embassy status. On 7 September 2012, Canada broke off diplomatic relations with Iran, saying "It is among the world's worst violators of human rights; and it shelters and materially supports terrorist groups." In a statement, Canadian foreign minister John Baird said "the Iranian regime has shown blatant disregard for the Vienna Convention and its guarantee of protection for diplomatic personnel. Under the circumstances, Canada can no longer maintain a diplomatic presence in Iran. Our diplomats serve Canada as civilians, and their safety is our number one priority." The announcement of embassy closure happened on the same day that the movie Argo, about the Canadian Caper, was released at the Toronto International Film Festival.

An era of close alliance between Shah Mohammad Reza Pahlavi's regime and the American government was followed by a dramatic reversal and hostility between the two countries after the 1979 Iranian Revolution. Currently, Iranian interests in the United States are handled through the Pakistani embassy. Opinions differ over what has caused the decades of poor relations. Explanations offered include everything from the "natural and unavoidable" conflict between the Islamic Revolution on the one hand, and American arrogance and desire for global dictatorship and hegemony on the other, to the regime's need for an "external bogeyman" to "furnish a pretext for domestic repression" against pro-democratic forces, and bind the regime to its "small but loyal and heavily armed constituency". |
| Venezuela | 9 August 1950 | See Iran–Venezuela relations Both countries established diplomatic relations on 9 August 1950.

The two presidents declared an "axis of unity" against "US imperialism". |

| Georgia | 15 May 1992 | See Georgia–Iran relations, Persia–Georgia relations Both countries established diplomatic relations on 15 May 1992. Iran and Georgia have had relations for hundreds of years. Georgia, throughout its history, has several times been annexed by the Persian Empire, specifically under the Achaemenid, Parthian, Sassanid, and Safavid dynasties. Accordingly, there has been a lot of political and cultural exchange, and Georgia was often considered a part of Greater Iran. Iran and Georgia, or the Georgian kingdoms, have had relations in different forms, beginning with trade in the Achaemenid era. The relationship got more complex as the Safavids took power in Iran and attempted to maintain Iranian control of the Georgian kingdoms. This continued until the 19th century when Russia, through the Russo-Persian War (1804–13) and Russo-Persian War (1826–1828), took the Caucasus from the Qajars, and thus Iran irrevocably lost the whole region, including Georgia. In the early 20th century, Iran–Georgian relations were merged into Iran–Soviet relations.

In the 1990s, India and Iran both supported the Northern Alliance in Afghanistan against the Taliban regime. India and Iran have had relations for millennia. With the growth of India's strategic and economic ties with the United States and the West in recent years, there have been instances of marked differences in diplomatic stances of the two countries on core issues.

There they established themselves, taking over the Lebanese Army's regional headquarters in the Sheikh Abdullah barracks, as well as a modern clinic, renamed "Hospital Khomeini", and the Hotel Khayyam. The Pasdaran were active in many places, including schools, where they propagated Islamic doctrine. Iranian clerics, most notably Fazlollah Mahallati, supervised. From this foothold, the Islamic Republic helped organize one of its biggest successes, the Hezbollah militia, a party and social-services organization devoted to the Khomeini principle of Guardianship (i.e. rule) of the Islamic Jurists (Velayat-e-Faqih), and loyal to Khomeini as their leader. Over the next seven years Iran is estimated to have spent $5 to $10 million US per month on Hezbollah, although the organization is now said to have become more self-sufficient. In the words of Hussein Musawi, a former commander of Amal militia who joined Hezbollah: We are her [Iran's] children. We are seeking to formulate an Islamic society which in the final analysis will produce an Islamic state. ... The Islamic revolution will march to liberate Palestine and Jerusalem, and the Islamic state will then spread its authority over the region of which Lebanon is only a part. United Nations Security Council Resolution 1559 (2 September 2004) called for the "disbanding and disarmament of all Lebanese and non-Lebanese militias".

After the 1971 war Iran tried to strengthen its ties with Pakistan's arch rival India. The Shah of Iran planned to annex the Balochistan province as Pakistan would surrender after a loss of the 1971 war. Following the Iranian revolution of 1979, Pakistan started having close relations with Saudi Arabia.

| Palestine | | See Iran–Palestine relations The Islamic Republic of Iran (established after the 1979 Iranian Revolution) closed the Israeli embassy in Tehran and replaced it with a Palestinian embassy. Iran favours a Palestinian state and officially endorses the replacement of Israel with a unitary Palestinian state or whatever choice the Palestinian people decide through a democratic vote. In a 2006 interview, Mohammad Khatami said Iran has also stated its willingness to accept a two-state solution if the Palestinians find this acceptable. The Iranian government regularly sends aid to various Palestinian causes, everything from transporting injured children to hospitals to supplying the Palestinian Islamist militant groups Islamic Jihad and Hamas with arms. Streets and squares named after Palestinians crisscross the nation. Several Palestinian militant resistance groups, including Hamas, are Iranian allies. The Iranian government also gives substantial assistance to the Hamas government in Gaza, which is embargoed by Israel, and depends on outside sources for an estimated 90% of its budget. Iranian support is not unconditional. In July and August 2011 Iran cut funding to show its displeasure at "Hamas's failure to hold public rallies in support" of Syrian President Bashar al-Assad during the Syrian Civil War. In part for this reason, Hamas was unable to pay July salaries of its "40,000 civil service and security employees." |

| Saudi Arabia | 24 August 1929 | See Iran–Saudi Arabia relations and Iran–Saudi Arabia proxy conflict Both countries established diplomatic relations on 24 August 1929. Due to various political and cultural clashes throughout history, relations between the two nations have been greatly strained. In 1966 King Faisal of Saudi Arabia visited Iran with the aim of further strengthening the relationships between the countries. The Shah (King) of Iran reciprocated by paying an official visit to Saudi Arabia, which eventually led to a peaceful resolution of a dispute concerning the islands of Farsi and Arabi: it was agreed that Farsi would belong to Iran and Arabi would be under the control of Saudi Arabia. A unique feature of this agreement is that it assigned only territorial waters to the islands, not the continental shelf. In 1968, when Great Britain announced its withdrawal from the Persian Gulf, Iran and Saudi Arabia took the primary responsibility for peace and security in the region. During the 1970s, Saudi Arabia's main bilateral concerns were Iran's modernization of its military, which was capable of dominating the entire region, and Iran's repossession of the Islands of Big Tunb, Little Tunb and Abu Moussa in 1971, challenging the United Arab Emirates' claim to the Islands. Despite these frictions, the friendliness of Iran–Saudi Arabia relations reached a peak in the period between 1968 and 1979. After the Iranian Revolution in 1979, Khomeini and other Iranian leaders openly attacked and criticized the character and religious legitimacy of the Saudi regime. According to Le Figaro, on 5 June 2010 King Abdullah of Saudi Arabia told Hervé Morin, the Defense Minister of France, "There are two countries in the world that do not deserve to exist: Iran and Israel." On 3 January 2016, Saudi Arabia severed diplomatic relations with Iran. Iran and Saudi Arabia restored relations in 2023. |

| Syria | 12 November 1946 | See Iran–Syria relations Both countries established diplomatic relations on 12 November 1946 when has been accredited Envoy Extraordinary and Plenipotentiary of Iran to Syria with residence in Beirut Mr. Zein-el-Abdine Rahnema. Syria was one of the few Arab countries to support Iran during the Iran–Iraq War, putting them at odds with other nations in the Arab League. Iran and Syria have had a strategic alliance ever since, partially due to their common animosity towards Saddam Hussein and coordination against the United States and Israel. Syria and Iran cooperate on arms smuggling from Iran to Hezbollah in Lebanon, which borders Israel. Iran was reported as helping Syria to suppress the anti-government protests that broke out in 2011 with training, munitions and high-tech surveillance technology. The Guardian reported in May 2011 that the Iranian Republican Guard increased its "level of technical support and personnel support" to strengthen Syria's "ability to deal with protesters", according to one diplomat in Damascus. Iran reportedly assisted the Syrian government sending it riot control equipment, intelligence monitoring techniques and oil. It also agreed to fund a large military base at Latakia airport. The Daily Telegraph has claimed in August that a former member of Syria's secret police reported "Iranian snipers" had been deployed in Syria to assist in the crackdown on protests. According to the US government, Mohsen Chizari, the Quds Force's third-in-command, has visited Syria to train security services to fight against the protestors. On 24 June 2011 The EU's official journal said the three Iranian Revolutionary Guard members now subject to sanctions had been "providing equipment and support to help the Syrian regime suppress protests in Syria". The Iranians added to the EU sanctions list were two Revolutionary Guard commanders, Soleimani and Brig Cmdr Mohammad Ali Jafari, and the Guard's deputy commander for intelligence, Hossein Taeb. |

Iran and Turkey also have very close trade and economic relations. Both countries are part of the Economic Cooperation Organization (ECO). Turkey receives about 2 million Iranian tourists each year and benefits economically from Iranian tourism. Bilateral trade between the nations is increasing. In 2005, bilateral trade increased to $4 billion from $1 billion in 2000. Iran's gas exports to Turkey are likely to increase. Turkey imports about 10 billion cubic meters a year of gas from Iran, about thirty percent of its needs. Turkey plans to invest $12 billion in developing phases 22, 23, and 24 of the South Pars gas field, a senior Iranian oil official told Shana.ir. Half of this gas will be re-exported to Europe. Two-way trade is now in the range of $10 billion (2008), and both governments have announced that the figure should reach the $20 billion mark in the not-too-distant future. Turkey won the tender for privatization of the Razi Petrochemical Complex, valued at $650 million (2008).

Trade between the two nations surpasses $1 billion and Iranians are the second-largest buyers of Turkmen commodities, mainly natural gas. The $139-million Korpeje-Kurt Kui gas pipeline in western Turkmenistan and the $167-million Dousti ("Friendship" in Persian) Dam in the south of the country were built through a joint venture. Their Caspian Sea territorial boundaries are a cause of tension between the two countries.

Bilaterally the two countries have an Air Transport Agreement. The Herald Tribune reported on 22 January 2006 a rise in British exports to Iran, from £296 million in 2000 to £443.8 million in 2004. A spokesperson for UK Trade and Investment was quoted to say "Iran has become more attractive because it now pursues a more liberal economic policy." In 2011, the UK together with the United States and Canada, issued sanctions on Iran following controversy over the country's nuclear program. As a result, Iranian government's Guardian Council approved a parliamentary bill expelling the British ambassador. On 29 November 2011, two compounds of the British embassy in Tehran were stormed by Iranian protesters. They smashed windows, ransacked offices, set fire to government documents, and burned a British flag.

The Iranian chargé d'affaires in London was simultaneously instructed to immediately close the Iranian embassy in London and given a 48-hour ultimatum for all staff to leave the UK. On Tuesday 17 June 2014 the Secretary of State for Foreign and Commonwealth Affairs, William Hague, announced that the UK embassy would re-open "as soon as practical arrangements are made".

The embassy reopened on 23 August 2015. On Friday 19 July 2019 a British-flagged oil tanker, the Stena Impero, was surrounded and seized by the Iranian Armed Forces at the Strait of Hormuz. The nearly 30,000 tonne tanker and its 23 crew members were surrounded by 4 vessels and 1 helicopter. Many think this was in retaliation of the UK boarding an Iranian Supertanker, the Grace 1, at Gibraltar earlier in July due to suspicions of smuggling oil to Syria. As of today, the tanker has been moved to the port of Bander Abbas and the ship's owners have not been able to contact the tanker. The British Foreign Minister Jeremy Hunt has said that Iran will suffer serious consequences if the tanker is not released. The British diplomatic effort is being supported by American President Donald Trump and both French and German foreign ministries. UK ships are urged to stay away from the strait and the result of this is an increase in oil prices around the world. |
