Reciprocity would be that American companies can access the Chinese market if they obey the same rules in the Chinese market that Chinese companies have to obey in the Chinese market, and Chinese companies can access the American market if they obey the same rules in the American market that American companies have to obey in the American market.

Facebook and others were in the Chinese market but they got blocked because they would not censor things that the Chinese government wanted censored and would not turn over user information that the government asked for. Chinese social media companies also are subject to those same censorship and user disclosure requirements, and will be banned (or worse) if they do not comply.

Would Facebook be allowed back in if they agreed to the censoring and to turning over user information? As far as I know none of the major American social media companies have been willing to do so, and so we don't know.
