The popularity of Twitter has produced a number of clones in China, just as there are Facebook clones. Some of China's Twitter clones have been closed down by the Chinese government, but some have survived. We take a look at both cases in this post.

Fanfou, Jiwai and Digu were some of the first Twitter clones to become successful in China.
