Canada, as chair this year, is in a unique position to help steer that conversation. The accession of new members to the CPTPP, though, is by consensus, and the reality is that, while Canada and some others have serious concerns about the entry of China, there are other members that would like China to enter.
I think a good process to follow in attempting to depoliticize these issues and not make it solely about China—because if we make it about China, China will make it about Taiwan and so on—is to follow clear criteria on things like to what extent countries allow foreign investment in and how they treat Canadian companies in their economies. Using the existing record of success or not to evaluate the applications and not accepting promises of behaviour change in the future as criteria would potentially allow a very large member to be accepted into the CPTPP.
