The west is constantly pushing for stuff like this in every trade policy with China and others...

There’s a limit to how much leverage any one side has on a sovereign countries policies (and how much they actually enforce them when they agree).

There’s also the question of the benefits of having China at all in these deals, some concessions and a growing dependence on western markets from initial deals is better than no deals.

Plus a wealthier China is good for the world and the billion people coming out of poverty, getting educated, and slowly becoming an advanced economy.
