The Forum for the Progress and Development of South America is an initiative by Sebastián Piñera and Iván Duque, for the creation of an integration body to replace the Union of South American Nations.

European integration is the process of industrial, economic, political, legal, social and cultural integration of states wholly or partially in Europe or nearby. European integration has primarily come about through the European Union and its policies.

The North American Union (NAU) is a theoretical economic and political continental union of Canada, Mexico and the United States, the three largest and most populous countries in North America. The concept is loosely based on the European Union, occasionally including a common currency called the amero or the North American Dollar. A union of the North American continent, sometimes extending to Central and South America, has been the subject of academic concepts for over a century, as well as becoming a common trope in science fiction. One reason for the difficulty in realizing the concept is that individual developments in each region have failed to prioritize a larger union. Some form of union has been discussed or proposed in academic, business, and political circles for decades. However, government officials from all three nations say there are no plans to create a North American Union and that no agreement to do so has been proposed, much less signed. The formation of a North American Union has been the subject of various conspiracy theories.

The Pacific Alliance is a Latin American trade bloc, formed by Chile, Colombia, Mexico and Peru, which all border the Pacific Ocean. The alliance was formed with the express purpose of improving regional integration and moving toward complete freedom in the movement of goods, services, capital and people between the four member states. Together, these four countries have a combined population of nearly 230 million people and make up roughly 35% of Latin American GDP.

Pan-Africanism is a worldwide movement that aims to encourage and strengthen bonds of solidarity between all indigenous and diaspora ethnic groups of African descent. Based on a common goal dating back to the Atlantic slave trade, the movement extends beyond continental Africans with a substantial support base among the African diaspora in the Americas and Europe.

Regional Integration is a process in which neighboring countries enter into an agreement in order to upgrade cooperation through common institutions and rules. The objectives of the agreement could range from economic to political to environmental, although it has typically taken the form of a political economy initiative where commercial interests are the focus for achieving broader socio-political and security objectives, as defined by national governments. Regional integration has been organized either via supranational institutional structures or through intergovernmental decision-making, or a combination of both.

The Union of South American Nations is an intergovernmental regional organization that once comprised twelve South American countries; as of 2019, most have withdrawn.
