China can retaliate by having a law like any US or European company or its subsidiary selling arms or take part in military project with Taiwan will be banned for doing business with China. To take it even to harder line any US or European company having trade relation with Taiwan in specific sectors like for example telecom, oil & gas, power grid, shipping, air travel, high tech etc will be banned in doing business with China.
I think its already happening .... but perhaps word "ban" is not used by Chinese govt ... more elegant wording
