Which might not be true. If the deal doesn't benefit the country, guess what will happen? Just don't sign it. Most of the TPP countries didn't have a bilateral agreement with US at this moment, so it is the status quo.

And since Trump's government is backtracking to protectionism, manufacturing jobs will less likely be delegated to countries like Vietnam, and countries like Japan doesn't have its back from US to confront China(Abe must be scratching his head right now, lol), I think it is much less appealing for those countries to hand over domestic control over regulations in exchange for something lesser.

Yes, that's true. But now people are aware of multinationals slipping sops to themselves into trade treaties. Every single bilateral agreement gets voted on in Senate for treaties, and both houses (?) for laws. Stakeholders like the bulk of the populace can be heard multiple times, once on each deal on these issues. One, fast-track vote on TPP where McConnell could stifle all debate procedurally is kind of a farce when nobody but multinationals negotiated it.
