Trump is trying to bully everyone into submission and when that fails, hit them with tariffs and sanctions. It's what he did during his first mandate when he invited his "very good friend" Xi at his Mar-a-Lago estate. When a deal regarding the DPRK nuclear prigram failed to materialize he began threatening China with tariffs. I don't see any reason why it would be different now, only more "ambitious".

The EU should have its own China policy irrespective of the Trump Administration's.
