Question: Eucharis and Aechmea, are in which two countries location?

Context paragraphs:
France–Netherlands relations: The French–Dutch relations refer to the interstate and bilateral relations between France and the Netherlands.  The two countries notably share a border division in the Caribbean island of Saint Martin, to which the northern part of the island is a French overseas collectivity known as the Collectivity of Saint Martin, while the southern part of the island is a Dutch constituent country known as Sint Maarten.  Relations between the two countries date back to the 17th and 18th centuries when a conflict led to the transformation of the Dutch Republic to the Batavian Republic and eventually the Kingdom of Holland.  The two countries currently enjoy close cultural and economic relations.  Both nations are members of the OECD, as well as founding members of the European Union, NATO, and the United Nations.

Saudi Arabia–United States relations: Bilateral relations between the Kingdom of Saudi Arabia and the United States began in 1933 when full diplomatic relations were established.  Despite the differences between the two countries—an ultraconservative Islamic absolute monarchy, and a secular, democratic republic—the two countries have been allies.  In recent years, the two countries have occasionally been described as having a "Special Relationship" with one another.  Former Presidents George W. Bush and Barack Obama have close and strong relations with senior members of the Saudi Royal Family.

Eucharis amazonica: Eucharis amazonica is a species of flowering plant in the family Amaryllidaceae, native to Peru.  It is cultivated as an ornamental in many countries and naturalized in Venezuela, Mexico, the West Indies, Ascension Island, Sri Lanka, Fiji, the Solomon Islands and the Society Islands.  The English name Amazon lily is used for this species, but is also used for the genus "Eucharis" as a whole (and for other genera).

The Farewell of Telemachus and Eucharis: The Farewell of Telemachus and Eucharis is an 1818 painting by Jacques-Louis David, now in the J. Paul Getty Museum.  It was a commission by count Franz Erwein von Schonborn-Wiesentheid during David's exile in Brussels.  It shows Telemachus and Eucharis, two characters in Fénelon's novel "Les Aventures de Télémaque", inspired by Homer's "Odyssey".  It was the artist's last painting to show a couple from mythology, it was a pendant painting to his "Love and Psyche".

France–United Kingdom relations: France–United Kingdom relations are the relations between the governments of the French Republic and the United Kingdom of Great Britain and Northern Ireland (UK).  The historical ties between the two countries are long and complex, including conquest, wars, and alliances at various points in history.  The Roman era saw both areas, except Scotland and Northern Ireland, conquered by Rome, whose fortifications exist in both countries to this day, and whose writing system introduced a common alphabet to both areas; however, the language barrier remained.  The Norman conquest of England in 1066 decisively shaped English history, as well as the English language.  In the medieval period, the countries were often bitter enemies, with both nations' monarchs claiming control over France.  The Hundred Years' War stretched from 1337 to 1453 resulting in French victory.  Britain and France fought a series of five major wars , culminating in the Coalition victory over Napoleon in 1815.  After that there were some tensions, but peace generally prevailed and as the 19th century progressed, the relationship became better.  Closer ties between the two began with the 1904 Entente cordiale, particularly via the alliances in World War I and World War II, wherein both countries fought against Germany, and in the latter conflict British armies helped to liberate occupied France from the Nazis.  Both nations opposed the Soviet Union during the Cold War and were founding members of NATO.  In recent years the two countries have experienced a quite close relationship, especially on defence and foreign policy issues; the two countries tend, however, to disagree on a range of other matters, most notably the European Union.  The British press relishes the chance to refer to France and Britain as "historic rivals" or emphasize the perceived ever-lasting competition that still opposes the two countries.

Soviet Union–United States relations: The relations between the United States of America and the Union of Soviet Socialist Republics (1922–1991) succeeded the previous relations from 1776 to 1917 and predate today's relations that began in 1992.  Full diplomatic relations between the two countries were established late due to mutual hostility.  During World War II, the two countries were briefly allies.  At the end of the war, the first signs of post-war mistrust and hostility began to appear between the two countries, escalating into the Cold War; a period of tense hostile relations, with periods of détente.

Malawi–Mozambique relations: Malawi–Mozambique relations refers to the current and historical relationship between the countries of Malawi and Mozambique.  As Malawi shares a large border with Mozambique, much of the substance of their foreign relations pertain to the border separating the two nations.  Both of the sovereign states have amicably agreed that lacustrine borders on Lake Malawi remain the largest priority between the two countries, as the exploitation of natural resources within the waters of Lake Malawi remain an issue the two countries continue to resolve.  The moment considered an act of generosity and sympathy within the two countries relations is when, during the Mozambique Civil War, Malawi housed over one million Mozambican refugees between 1985 and 1995.  After this gesture, Malawian relations with Mozambique crumbled under the tenure of Bingu wa Mutharika, notoriously reaching a nadir when Malawian police launched a raid into Mozambique's territory.

Eucharis (plant): Eucharis is a genus of about 15-20 species of Neotropical plants in the Amaryllis family, native to Central America and South America, from Guatemala south to Bolivia.  Some species have become naturalized in Mexico, the West Indies, and scattered tropical islands.  The English name Amazon lily is sometimes used for all species in the genus (as well as other genera), but is particularly used for "Eucharis amazonica" and "Eucharis" × "grandiflora", which are often confused.

Aechmea: Aechmea is a genus in the botanical family Bromeliaceae, subfamily Bromelioideae.  The name comes from the Greek “aichme” (a spear).  "Aechmea" has 8 subgenera and 255 species distributed from Mexico through South America.  Most of the species in this genus are epiphytes.

Covered interest arbitrage: Covered interest arbitrage is an arbitrage trading strategy whereby an investor capitalizes on the interest rate differential between two countries by using a forward contract to "cover" (eliminate exposure to) exchange rate risk.  Using forward contracts enables arbitrageurs such as individual investors or banks to make use of the forward premium (or discount) to earn a riskless profit from discrepancies between two countries' interest rates.  The opportunity to earn riskless profits arises from the reality that the interest rate parity condition does not constantly hold.  When spot and forward exchange rate markets are not in a state of equilibrium, investors will no longer be indifferent among the available interest rates in two countries and will invest in whichever currency offers a higher rate of return.  Economists have discovered various factors which affect the occurrence of deviations from covered interest rate parity and the fleeting nature of covered interest arbitrage opportunities, such as differing characteristics of assets, varying frequencies of time series data, and the transaction costs associated with arbitrage trading strategies.
