WeChat is available in other languages like English, but network effect is weak outside of China. So you can order takeout and ride share in China with WeChat but nowhere else. Payment is also only in China.
Pony Ma was supposed to meet with WhatsApp founders to discuss acquisition but had to postpone the trip to have back surgery. Zuck stole WA instead. To this date I still don’t understand how come Zuck didn’t just copy WeChat. With mini programs WeChat is on its way to steal big shares from Apple and Android app stores. WhatsApp doesn’t even have payments except in India. It’s progressing at a snail pace.
