Next month I need to make a quick trip to Shanghai to open a Chinese bank account.

The good news is that I can fly there without a visa on a UK passport, and transit there for up to 6 days in the City.

I then want to return to Chiang Mai on another 60 day SETV but I cannot go directly back to Thailand as that would mean my visit to China wasn't a transit and also I don't believe China issues Thailand SETV to non nationals anyway.

What would be the best flight/Thailand SETV visa options from Shanghai to another country and then back to Chinag Mai? HK, Malaysia are options as both would allow visa free entry on UK passport.

Also, would I need to show in my SETV application proof of onward travel out of Thailand or just proof of funds and accommodation? Thanks
