I am a British citizen with a valid Chinese tourist visa is an expired passport, and I have a new passport. I've heard reports that it's fine to enter China like this, despite the fact that officially on the UK visa for China application website it says you can't (I once phoned and the woman said it was fine, despite what it says on the website). Can anyone comment? (British passport holders only!)
Secondly, my embarkation point is Tajikistan (Dushanbe) flying to Ürümqi in China, not from the UK. Will this be OK to fly according to Timatic? I will probably be flying with a Chinese airline.
