European countries have a large trade deficit with China (€170B)[1]. The U.S. had about double the amount of trade deficit ($336B), mostly due to its greater value of imports [2].
This doesn't prove that China restricts access to its markets by European companies, but it provides evidence that the situation may not be as simple as you suggest.
