I am a British citizen who has been living and working in Shanghai for 20 years. In Feb this year, I returned to UK for a brief visit and since, I hv been unable to return to China due to restrictions re world C19 situation.
I need to return to Shanghai asap, but I don't know if I will be able to gain entry into China due to the pandemic. I have a valid Work permit (cat B) and a valid visa …. please can anyone tell me whether or not I will be allowed into China when I plan to go there late July? Any quarantine on arrival? Thank you.
