Taiwan qualifies already. There's no question about that. China does not qualify, so we have an obvious political issue here, except that we already have some international or transnational agreements where you have membership that is not limited to states. For example, we have Taiwan's customs territory in the World Trade Organization.
Unfortunately, to my knowledge, the CPTPP is between states, so we may have to send a signal that Taiwan should be welcome in the CPTPP. I believe that.
