On 3/21, several media reported that the People's Bank of China* would ban all the bitcoin trading in China. This was later proved to be wrong. The People's Bank of China made a announcement on n weibo (the Chinese version of twitter) that this was a false interpretation. But it didn't come with a correct version.
On 3/26, one of the largest financial media, Caixin, confirmed the actual message sent by People's Bank of China. It requires that all the banks and 3rd party payment services stay away from bitcoin trading platform, making it impossible to fund or withdraw money. The deadline is 4/15.
*People's bank of China is actually NOT a bank. It is a regulatory agency controlling all the financial activities.
