And for that reason, I am against it. The reforms after WTO joining didn't happen in isolation. It was a continuation of reforms initiated a decade or more before by Deng. One could say China ably used the myopia /tunnel vision/ cataract the west had during the post Soviet collapse decades.
I certainly believe CPTPP will force China to reform, but this time its going to harm the country. The west has a vision impairment of a different kind (maybe brain) that sees China as the boogeyman. Having China be forced to change for CPTPP creates openings of weaknesses the adversaries can exploit. It's not even a possibility but a certainty. I would have tried to do damage using CPTPP if I were a US / Five eyes Foreign affairs planner.
Simply put, be wary of any groupings, arrangements, blocs, motions, initiatives etc led by adversarial western countries or Allies after 2010.
I really hope so. But again, if I were a CPTPP diplomat, I'd welcome China, expedite the process of integration and then gift the Chinese a thousand cuts.
