A better deal in a "free trade agreement" is just that - a free trade agreement. Enforcement and length of IP rights, the ability of corporations to extrajudicially sue governments, GMOs (as is the case in the Trans-Atlantic trade agreement) etc. has nothing to do with free trade, i.e. trade without import taxes.
The TPP is not merely a free trade deal. It is a trade deal made exclusively to isolate China, and then allow it to participate in a few years only if it (China) follows certain rules (i.e. Western Intellectual Property law).
