The People's Republic of China is not a free country, and the United States of America is. In contrast to @SecPompeo, I have no problem with that "lack of reciprocity" continuing. https://www.state.gov/advancing-reciprocity-in-u-s-china-diplomatic-relations/

The Chinese government's restrictions on US diplomats are also restrictions on the Chinese people.

By the same token, the US government's restrictions on Chinese diplomats, in the name of "reciprocity", are also restrictions on the American people.

I don't give a hoot about being "fair" to Beijing, as some will imagine is my motivation. I care deeply about that kind of country WE have, and that it taps its own strengths instead of trying to imitate others who it should not imitate.
