Until a few weeks ago, Long Zhenyang held one of the top mediajobs in south China.
He was the assistant chief editor of the Hong Kong Commercial Daily, one of three pro-Beijing newspapers in the Chinese territory.
Mr Long, 47, has told BBC News that he left mainland China because he had been "persecuted" at the newspaper since late 2014, after he shared posts on his private social media account that were supportive of the pro-democracy protests in Hong Kong.
A devout Christian, the former journalist said he was also upset by a long-running campaign to remove crosses from churches in the eastern Chinese province of Zhejiang.
