From today's Hong Kong Standard:
"Also yesterday, Tencent said foreigners living in Hong Kong, Macau and Taiwan can now connect to Weixin Pay through any international credit cards. This is the first time that people will not need to have a Chinese bank account or credit card to take advantage of the country's fast-growing cashless payment system that makes it easier to shop and pay for daily needs online."
