You’re absolutely right that the chinese market is much larger and could exert this force if it wanted to, but the EU rarely makes these types of moves, and they’re normally focusing on consumer protection (think GDPR), which I don’t think the CCP is really focused on.
Even so, the EU is large enough that if they legislated changes, like they did with Phone charging ports, companies will fall in line so as not to miss out on a big market for their products. Results may differ for digital products though.
