Russia has blocked China's largest messaging app, WeChat. The Russian communication regulator added the platform to its list of prohibited services, after the app was found not to comply with information distribution laws. WeChat's owner, Tencent, has said that it is in contact with Russian authorities to resolve the issue as soon as possible. Russian laws require that social media platforms store Russian user data in the country, which in the past has led to the blockage of sites like LinkedIn. Tencent has claimed that it did not understand the rules. WeChat is no stranger to censorship. In its homeland of China, authorities have blocked WeChat messages including phrases such as 'Tiananmen Square' or 'Tibet' for several years. A Russian-relations expert at the Chinese Academy of Social Sciences said however that he does not believe the block in Russia to be politically motivated.
