A Taiwanese newspaper editor was being questioned by security authorities in Xinjiang last night. Lee Fu-chung, an editor of Central Daily, a newspaper associated with the Kuomintang, was being held by police in the regional capital Urumqi for 'engaging in activities incompatible with his status as a journalist', officials said. Xinjiang's Taiwan Affairs Office was still mediating with security officials last night in a bid to find out if Mr Lee had violated any laws while on the mainland. It was not clear if his detention was in connection with his reports about separatist activities within Xinjiang. Mr Lee, a member of the KMT, had planned to travel to Yili district today accompanied by another Taiwanese reporter. The editor was last in contact with his colleagues in Taipei on Monday night when he said he had problems trying to transmit his articles to his newspaper from his hotel. It was believed that Mr Lee was detained after he sent his reports from another hotel. The editor, who is in his 30s, travelled to the northwestern region last Wednesday to cover the annual Urumqi Trade Fair. Other reporters covering the event reported his disappearance to the Taiwan Affairs Office. The event has attracted less interest than in the past years.
