RCEP is the abbreviation of English RegionalCom - prehensiveEconomicPartnership.It is the first regional economic integration cooperation proposed by ASEAN countries in recent years and led by ASEAN. It is a form of organization in which member countries open their markets to each other and implement regional economic integration.The RCEP's main members plan to include countries that have signed free trade agreements with ASEAN, namely China, Japan, South Korea, Australia, New Zealand and India.The 10 ASEAN countries have signed five free trade agreements with each of the six, including a free trade agreement with Australia and New Zealand.These 16 countries are currently planned to form the RCEP. The other two EAS members (the US and Russia) do not have free trade relations with ASEAN, so they are not included in the RCEP member countries' plan.Asean plans to negotiate the accession of the United States and Russia after the 16 countries have built the RCEP to a certain extent.
