China has demanded that the US apologises for sheltering blind activist Cheng Guangcheng in its embassy in Beijing, the official Xinhua news agency said.
Chen, who angered Chinese authorities by exposing forced abortions and sterilisations under the "one-child" policy, left the embassy on Wednesday and was taken to join his family, a US official said.
The official, who spoke on condition of anonymity, did not give additional details on Chen's whereabouts or condition.
Chen, a legal activist, escaped from house arrest late last month and was believed to have been in Beijing under US protection.
Xinhua reported that Chen left the US embassy after staying there for six days. Source
