Regional Comprehensive Economic Partnership in the context of "Regional integration"

A free trade area is the region encompassing a trade bloc whose member countries have signed a free trade agreement (FTA). Such agreements involve cooperation between at least two countries to reduce trade barriers, import quotas and tariffs, and to increase trade of goods and services with each other. If natural persons are also free to move between the countries, in addition to a free trade agreement, it would also be considered an open border. It can be considered the second stage of economic integration.

Customs unions are a special type of free trade area. All such areas have internal arrangements which parties conclude in order to liberalize and facilitate trade among themselves. The crucial difference between customs unions and free trade areas is their approach to third parties. While a customs union requires all parties to establish and maintain identical external tariffs with regard to trade with non-parties, parties to a free trade area are not subject to this requirement. Instead, they may establish and maintain whatever tariff regime applying to imports from non-parties as deemed necessary. In a free trade area without harmonized external tariffs, to eliminate the risk of trade deflection, parties will adopt a system of preferential rules of origin.

The ASEAN Free Trade Area (AFTA) is a trade bloc agreement by the Association of Southeast Asian Nations supporting local trade and manufacturing in all ASEAN countries, and facilitating economic integration with regional and international allies. It stands as one of the largest and most important free trade areas (FTA) in the world, and together with its network of dialogue partners, drove some of the world's largest multilateral forums and blocs, including Asia-Pacific Economic Cooperation, East Asia Summit and Regional Comprehensive Economic Partnership.

The AFTA agreement was signed on 28 January 1992 in Singapore. When the AFTA agreement was originally signed, ASEAN had six members, namely, Brunei, Indonesia, Malaysia, Philippines, Singapore and Thailand. Vietnam joined in 1995, Laos and Myanmar in 1997 and Cambodia in 1999. AFTA now comprises the ten countries of ASEAN. All the four latecomers were required to sign the AFTA agreement to join ASEAN, but were given longer time frames in which to meet AFTA's tariff reduction obligations.

The Comprehensive and Progressive Agreement for Trans-Pacific Partnership (CPTPP), previously abbreviated as TPP11 or TPP-11 before enlargement, is a multilateral trade agreement between Australia, Brunei, Canada, Chile, Japan, Malaysia, Mexico, New Zealand, Peru, Singapore, the United Kingdom and Vietnam.

The twelve members have combined economies representing 14.4% of global gross domestic product, at approximately US$15.8 trillion, making the CPTPP the world's fourth largest free trade area by GDP, behind the United States–Mexico–Canada Agreement, the European single market, and the Regional Comprehensive Economic Partnership.
