Mega-regional trade deals require economies to forge appropriate policy responses to navigate implementation challenges and unlock potential opportunities. The Regional Comprehensive Economic Partnership (RCEP), which entered into force on 1 January 2022, is no exception. 1 Partnering 10 Southeast Asian nations with Australia, the People's Republic of China (PRC), Japan, the Republic of Korea, and New Zealand, RCEP is the most recent plurilateral initiative to foster regional cooperation and integration in Asia and the Pacific. 2 As a strong commitment to open, transparent, and inclusive trade and investment regimes, the agreement is expected to strengthen the region's manufacturing supply chains, raise productivity, and increase wages and employment, with world income gains estimated at $263 billion (Park, Petri, and Plummer 2021).At the same time, compared to the Comprehensive and Progressive Agreement for Trans-Pacific Partnership (CPTPP) and other agreements in Asia and the Pacific, RCEP does not provide strong disciplines in new areas and has been qualified as a "shallow" agreement.
