Trade bloc in the context of "Customs union"

An economic union is a type of trade bloc which is composed of a common market with a customs union. The participant countries have both common policies on product regulation, freedom of movement of goods, services and the factors of production (capital and labour) as well as a common external trade policy. When an economic union involves unifying currency, it becomes an economic and monetary union.

The purposes for establishing an economic union normally include increasing economic efficiency and establishing closer political and cultural ties between the member countries.

The European Free Trade Association (EFTA) is a regional trade organisation and free trade area consisting of four European states: Iceland, Liechtenstein, Norway and Switzerland. The organisation operates in parallel with the European Union (EU), and all four member states participate in the European single market and are part of the Schengen Area. They are not, however, party to the European Union Customs Union.

EFTA was historically one of the two dominant western European trade blocs, but is now much smaller and closely associated with its historical competitor, the European Union. It was established on 3 May 1960 to serve as an alternative trade bloc for those European states that were unable or unwilling to join the then European Economic Community (EEC), the main predecessor of the EU. The Stockholm Convention (1960), to establish the EFTA, was signed on 4 January 1960 in the Swedish capital by seven countries (known as the "Outer Seven": Austria, Denmark, Norway, Portugal, Sweden, Switzerland and the United Kingdom). A revised Convention, the Vaduz Convention, was signed on 21 June 2001 and entered into force on 1 June 2002.

A single market, sometimes called common market or internal market, is a type of trade bloc in which most trade barriers have been removed (for goods) with some common policies on product regulation, and freedom of movement of the factors of production (capital and labour) and of enterprise and services. The goal is that the movement of capital, labour, goods, and services between the members is as easy as within them. The physical (borders), technical (standards) and fiscal (taxes) barriers among the member states are removed to the maximum extent possible. These barriers obstruct the freedom of movement of the four factors of production (goods, capital, services, workers).

A common market is usually referred to as the first stage towards the creation of a single market. It usually is built upon a free trade area with no tariffs for goods and relatively free movement of capital, workers and services, but not so advanced in reduction of other trade barriers.

An economic and monetary union (EMU) is a type of trade bloc that features a combination of a common market, customs union, and monetary union. Established via a trade pact, an EMU constitutes the sixth of seven stages in the process of economic integration. An EMU agreement usually combines a customs union with a common market. A typical EMU establishes free trade and a common external tariff throughout its jurisdiction. It is also designed to protect freedom in the movement of goods, services, and people. This arrangement is distinct from a monetary union (e.g., the Latin Monetary Union), which does not usually involve a common market. As with the economic and monetary union established among the 27 member states of the European Union (EU), an EMU may affect different parts of its jurisdiction in different ways. Some areas are subject to separate customs regulations from other areas subject to the EMU. These various arrangements may be established in a formal agreement, or they may exist on a de facto basis. For example, not all EU member states use the Euro established by its currency union, and not all EU member states are part of the Schengen Area. Some EU members participate in both unions, and some in neither.

Territories of the United States, Australian External Territories and New Zealand territories each share a currency and, for the most part, the market of their respective mainland states. However, they are generally not part of the same customs territories.

The North American Free Trade Agreement (Spanish: Tratado de Libre Comercio de América del Norte, TLCAN; French: Accord de libre-échange nord-américain, ALÉNA), referred to colloquially in the Anglosphere as NAFTA, (/ˈnæftə/ NAF-tə) was an agreement signed by Canada, Mexico, and the United States that created a trilateral trade bloc in North America. The agreement came into force on January 1, 1994, and superseded the 1988 Canada–United States Free Trade Agreement between the United States and Canada. The NAFTA trade bloc formed one of the largest trade blocs in the world by gross domestic product.

The impetus for a North American free trade zone began with U.S. president Ronald Reagan, who made the idea part of his 1980 presidential campaign. After the signing of the Canada–United States Free Trade Agreement in 1988, the administrations of U.S. president George H. W. Bush, Mexican president Carlos Salinas de Gortari, and Canadian prime minister Brian Mulroney agreed to negotiate what became NAFTA. Each submitted the agreement for ratification in their respective capitals in December 1992, but NAFTA faced significant opposition in both the United States and Canada. All three countries ratified NAFTA in 1993 after the addition of two side agreements, the North American Agreement on Labor Cooperation (NAALC) and the North American Agreement on Environmental Cooperation (NAAEC).

The Southern Common Market (commonly known by abbreviation Mercosur in Spanish and Mercosul in Portuguese) is a South American trade bloc established by the Treaty of Asunción in 1991 and Protocol of Ouro Preto in 1994. Its full members are Argentina, Bolivia, Brazil, Paraguay, and Uruguay. Venezuela is a full member but has been suspended since 1 December 2016. Chile, Colombia, Ecuador, Guyana, Panama, Peru, and Suriname are associate countries.

Mercosur's origins are linked to the discussions for the constitution of a regional economic market for Latin America, which go back to the treaty that established the Latin American Free Trade Association in 1960, which was succeeded by the Latin American Integration Association in the 1980s. At the time, Argentina and Brazil made progress in the matter, signing the Iguaçu Declaration (1985), which established a bilateral commission, which was followed by a series of trade agreements the following year. The Integration, Cooperation and Development Treaty, signed between both countries in 1988, set the goal of establishing a common market, which other Latin American countries could join. Paraguay and Uruguay joined the process and the four countries became signatories to the Treaty of Asunción (1991), which established the Southern Common Market, a trade alliance aimed at boosting the regional economy, moving goods, people among themselves, workforce and capital. Initially a free trade zone was established, in which the signatory countries would not tax or restrict each other's imports. As of 1 January 1995, this area became a customs union, in which all signatories could charge the same quotas on imports from other countries (common external tariff). The following year, Bolivia and Chile acquired membership status. Other Latin American nations have expressed interest in joining the group.

The Agreement between the United States of America, the United Mexican States, and Canada (USMCA) is a free trade agreement among the United States, Mexico, and Canada, in effect from July 1, 2020. It replaced the North American Free Trade Agreement (NAFTA) implemented in 1994. Further, it is sometimes characterized as "NAFTA 2.0", or "New NAFTA", since it largely maintains or updates the provisions of its predecessor. The region including Canada, Mexico, and the United States is one of the world's largest free trade zones, with a population of more than 510 million people and an economy of $30.997  trillion in nominal GDP – nearly 30 percent of the global economy, and the largest of any trade bloc in the world.

All sides came to a formal agreement on 1 October 2018, and U.S. president Donald Trump proposed USMCA during the G20 Summit the following month, where he signed it, Mexican president Enrique Peña Nieto, and Canadian prime minister Justin Trudeau. A revised version reflecting additional consultations was signed on December 10, 2019. It was ratified by all three countries, with Canada being the last to ratify on March 13, 2020. Following notification by all three governments that the provisions were ready for domestic implementation, the agreement came into effect on 1 July 2020.
