Incredibly, WeChat Pay in China is now easy for foreigners: submit a copy of passport, link a debit account, and you can use WeChat Pay with no problems. No physical presence in China required, and the only restriction is that you can't use it abroad (i.e., at WeChat Pay stores outside of China). I've had a fully working WeChat Pay account for a couple years now, and I've never once had to do anything in-person or anything except upload my passport and Tencent made it happen.
