Chinese officials are threatening a "strike back" Friday after President Trump signed the TAIPEI Act, which ensures stronger US support for Taiwan, and calls for US action against anyone who undermines Taiwanese prosperity.

Resolutions calling for more US support for Taiwan are common, and China's response, criticizing it as "crude interference" in their internal affairs, is likewise common. Taiwan is not, after all, an independent country in practice, but a competing Chinese government.

These resolutions and responses are obligatory, but largely empty, as the US and China for the most part don't actually do anything related to the issue. The nations' respective coronavirus problems make it even less likely they'll get confrontational right now.
