This research uses simple descriptive analysis and a trade complementarity index to examine the Indonesia-RCEP agricultural trade relationship for the 2010-2019 period to predict future trade conditions for Indonesia RCEP. Based on the trade balance, starting from 2016 there has been an increase in trade exports, even in the last 4 years Indonesia has continued to experience a surplus of USD 36.93 billion. Throughout the decade, there was a match between the export supply of Indonesian agricultural products and the demand for imports of RCEP agricultural products because the agricultural product trade complementarity index was located between 86.95 and 90.09. The country with the highest TCI value compared to Indonesia is Singapore, whereas the country with the lowest TCI is Brunei Darussalam. The history of high TCI values has been proven to be followed by increasing in exports of agricultural products in 2020 to 2022 of up to 11 percent. The main exports of agricultural products with the highest TCI values are live animals (HS 01), live trees and other plants (HS 06), and vegetable resins (HS 13). Through the results of this research, it can be recommended that efforts to increase Indonesian exports to RCEP require contributions and intervention from the Indonesian government. In particular, in the form of providing incentives so that agricultural resources that are not yet optimally used can be utilized. Apart from that, the government needs to optimize the use of FDI which is RCEP's superior product to maximize the quantity, quality of production, integration of knowledge and technology.
