I was thinking more about the possibility of China pursuing a phased approach of allowing some foreigners to re-enter but not all at the same time - and then if so, what kind of criteria would they use? Number of COVID cases per country? Volume of trade? Travel reciprocity? Public praise? Etc. It's also worth noting, probably, that the United States still has its own travel ban in place on all foreigners from and who have been to China in the past 14 days.
