China asserts that "Rumors violate individual rights; rumors create social panic; rumors cause fluctuations in the stock markets; rumors impact normal business operations; rumors blatantly attack revolutionary martyrs." 

China has launched a platform, which includes a mobile app, that lets the public report "online rumours" and even uses artificial intelligence to identify reports that are false, as Beijing cracks down on what it views as socially destabilising content.

The platform, launched on Wednesday, comes as Beijing steps up efforts to police the internet, especially social media used by people to discuss politics and other sensitive subjects, despite stringent censorship.
