David Cameron has joined Sina Weibo. The British Prime Minister joined the social network — a popular Chinese microblogging platform similar to Twitter — on November 29th, ahead of a planned diplomatic visit to China. Camerons first message was used to greet friends in China in both English and Mandarin Chinese. Some Weibo users questioned the authenticity of Camerons account, but the British Embassy in Beijing confirmed Camerons participation, saying that Big boss had come to Weibo.
