So if WeChat is basically the only messaging app allowed in China, and WeChat is not allowed to be used in India, is there any widely available platform that Indian citizens can use to chat with Chinese citizens? Making it impossible or at least very difficult to communicate with people in another country seems like it’s only going to make any divide even worse in the long term. Think of the fallout of Facebook filter bubbles but to an extreme, by making it very difficult to even communicate with someone in a different culture with different viewpoints.

I agree. I made a website which breaks down failures and resolutions.
