Depends how you do it, doesn't it?
If you allow China to undercut your manufacturing base and you offshore everything you have, where are you?

Let's check in with the Europeans' auto sector:

China's got a growing share of Europe's EV market and is closing in on a monopoly on batteries.

The U.S. is signaling that it is very unwilling to tolerate Canada diverging from U.S. foreign policy preferences.

No we aren't. Just because state-controlled CBC says something or "Elbows up" Carney says something that hardly makes it true. Ever notice how nobody ever published this supposedly toxic trade agreement?

It means they couldn't negotiate trade agreements with China that differ from our China trade policy.

Does it? Have you seen the actual text and what it says?

They couldn't reach the "win-win," because the U.S. wanted to leverage our dominance in the trade relationship to force them to make concessions that they felt were an overall loss.

Again, no one's seen the actual deal so comments like these are premature at best and/or outright wrong.

We're trying to lock up the Western Hemisphere's supply chain provenance and make it less reliant on China. Why this is a bad thing in certain intellectual circles is beyond me.
