WeChat Pay is still a no-go, but you can now set up Alipay with any foreign credit/debit card, no need for the former rigmarole of account verification with Chinese phone number/bank account. And Alipay is accepted basically everywhere. (Cash is not.)
China is an absolute unbelievable pain due to being largely WeChat payment based now and there's a lot of restrictions on who can set this up.
