The Regional Comprehensive Economic Partnership (RCEP /ˈɑːrsɛp/ AR-sep) is a free trade agreement among the Asia-Pacific countries of Australia, Brunei, Cambodia, China, Indonesia, Japan, South Korea, Laos, Malaysia, Myanmar, New Zealand, the Philippines, Singapore, Thailand, and Vietnam. The 15 member countries account for about 30% of the world's population (2.2 billion people) and 30% of global GDP ($29.7 trillion), making it the largest trade bloc in history. Signed in November 2020, RCEP is the first free trade agreement among the largest economies in Asia (excluding India), including China, Indonesia, Japan, and South Korea.
The RCEP was conceived at the 2011 ASEAN Summit in Bali, Indonesia, while negotiations formally launched during the 2012 ASEAN Summit in Cambodia. India, which took part in the initial negotiations but later decided to opt out, was invited to join the bloc at any time. Any other country or separate customs territory in the region can accede to the pact from 1 July 2023 onward. The treaty was formally signed on 15 November 2020 at the virtual ASEAN Summit hosted by Vietnam. For the first ten ratifying countries, the trade pact took effect on 1 January 2022.
