China said to be holding Japan-based professor

A Chinese specialist in Sino-Japanese affairs who has been living in Japan appears to have been detained by the Chinese government since late July and is being questioned about his activities, according to Chinese academics and a Japanese newspaper, writes Jane Perlez for The New York Times.

News of the apparent detention comes as relations between China and Japan have hit their lowest point in decades, and has sent tremors of fear through the small communities of Chinese and Japanese academics who live in each other’s countries.

The Chinese government hinted but declined to confirm that the specialist, Zhu Jianrong, a professor at a university near Tokyo, was in custody after he travelled to his native Shanghai for a meeting on 17 July. The Japan Times recently reported his detention in an editorial on 29 September, without citing a source.
