We made a conscious decision at the outset to not reopen the text of the agreement, and specifically to not reopen market access. Our collective belief was that if we started to open up the texts and the market access provisions, the whole process would unravel.
Similarly, we had a very ambitious, robust environment chapter already negotiated. The environmental provisions in the CPTPP are subject to the dispute settlement mechanism. Therefore, they are binding and enforceable commitments. We didn't feel the need to add any side letters related to environment, given the ambitious nature of the chapter itself.
