If you mean our military bases in Japan and South Korea, who have no great trust of China, I'm not sure why China's opinion would be relevant there. If it's not controversial for Britain to offer them citizenship then it shouldn't be for US either. Even if it is...you gotta stand up to communism.

China objects strongly. It says these are Chinese citizens and Britain ceased to have any claim over the territory decades ago.
Of course since Britain's offer exists only on paper (there is no mechanism proposed by which a typical person in Hong Kong should actually make use of the offer to leave) the Chinese objection likewise extends only to paper.
