The inequity of being permitted to use WeChat and other social media to disseminate nonsense to the Chinese diaspora is a major problem. If WhatsApp Or Facebook can’t be in a China, then why is WeChat global? It’s also their key communication tool to permit them a sense that Chinese, everywhere, are still governed by the one China. Wechat has to be stopped. The first avenue would be standard legal practice - why are you disseminating lies in my country. Take them to court. But it has to be stopped also to provide a decent lever in future trade negotiations.
