RCEP and TPP, if successful, will be unprecedented accomplishments for economic integration in the Asia-Pacific. It will seek not only to deepen regional integration but also to facilitate trade through international production networks. However, the economic value of RCEP and TPP will depend on what is finally agreed upon and included in the final agreement. It will depend on the extent to which the agreement can strive for deeper “behind the border” integration measures, and reach an acceptable compromise on the challenging issues. Implementation integrity from all participating members will also be a key to its potential success.
