Just spoke with my TA. She called Celeb and cannot get a confirmation of anything regarding the 24 hour exemptions. They have given her various answers from “ you should be ok” to “ it’s not for us to advise”....Celeb Covering their butts...(.She is trying to get a response from the Chinese embassy ..( we are Canadian)
from all I’ve found on the web today, because we ARE going from Japan to China (Shanghai) then we make that technical stop in Korea before continuing to Taiwan we are ok. It’s only if you go from Shanghai to Taiwan or to another mainland China stop that negates the visa. Having said that I’m not an expert and am only offering my personally obtained info that I interpret from various websites.
I will update when I get a sure fire definitive answer from my TA.
