The United Nations (UN) is an intergovernmental organization whose purpose is to maintain international peace and security, develop friendly relations among nations, achieve international cooperation, and be a centre for harmonizing the actions of nations.

It is the world’s largest and most familiar international organization. The UN is headquartered on international territory in New York City, and has other main offices in Geneva, Nairobi, Vienna, and The Hague (home to the International Court of Justice).

The organization’s mission to preserve world peace was complicated in its early decades by the Cold War between the United States and Soviet Union and their respective allies. Its missions have consisted primarily of unarmed military observers and lightly armed troops with primarily monitoring, reporting and confidence-building roles. UN membership grew significantly following widespread decolonization beginning in the 1960s.

Costa Rica (UK: /ˌkɒstə ˈriːkə/, US: /ˌkoʊstə/ ( listen); Spanish: [ˈkosta ˈrika]; literally “Rich Coast”), officially the Republic of Costa Rica (Spanish: República de Costa Rica), is a country in Central America, bordered by Nicaragua to the north, the Caribbean Sea to the northeast, Panama to the southeast, the Pacific Ocean to the southwest, and maritime border with Ecuador to the south of Cocos Island. It has a population of around five million in a land area of 51,060 km2 (19,710 sq mi). An estimated 333,980 people live in the capital and largest city, San José, with around two million people in the surrounding metropolitan area.

The sovereign state is a unitary presidential constitutional republic. It is known for its long-standing and stable democracy, and for its highly educated workforce. The country spends roughly 6.9% of its budget (2016) on education, compared to a global average of 4.4%.[13] Its economy, once heavily dependent on agriculture, has diversified to include sectors such as finance, corporate services for foreign companies, pharmaceuticals, and ecotourism. Many foreign manufacturing and services companies operate in Costa Rica’s Free Trade Zones (FTZ) where they benefit from investment and tax incentives.

Asia is Earth’s largest and most populous continent, located primarily in the Eastern and Northern Hemispheres. It shares the continental landmass of Eurasia with the continent of Europe, and the continental landmass of Afro-Eurasia with Africa and Europe. Asia covers an area of 44,579,000 square kilometres (17,212,000 sq mi), about 30% of Earth’s total land area and 8.7% of the Earth’s total surface area. The continent, which has long been home to the majority of the human population, was the site of many of the first civilizations. Its 4.7 billion people  constitutes roughly 60% of the world’s population.

In general terms, Asia is bounded on the east by the Pacific Ocean, on the south by the Indian Ocean, and on the north by the Arctic Ocean. The border of Asia with Europe is a historical and cultural construct, as there is no clear physical and geographical separation between them. It is somewhat arbitrary and has moved since its first conception in classical antiquity. The division of Eurasia into two continents reflects East–West cultural, linguistic, and ethnic differences, some of which vary on a spectrum rather than with a sharp dividing line. A commonly accepted division places Asia to the east of the Suez Canal separating it from Africa; and to the east of the Turkish Straits, the Ural Mountains and Ural River, and to the south of the Caucasus Mountains and the Caspian and Black Seas, separating it from Europe.
