US Under-Secretary of State Peter Tarnoff will visit China next week for follow-up talks on the recent meeting in Brunei between American and Chinese foreign ministers. The State Department said yesterday Mr Tarnoff would renew the push for the release of American-Chinese human rights activist Harry Wu Hongda, as well as discussing a full range of issues, including Taiwan. Mr Tarnoff will arrive in Shanghai next Thursday and go to Beijing the following day for talks with Vice-Foreign Minister Li Zhaoxing. He will leave on August 27. Mr Tarnoff's trip continues the high-level dialogue between the US and China that resumed on August 1 when Secretary of State Warren Christopher met Foreign Minister Qian Qichen in Brunei. Before that, China had halted high-level exchanges after President Bill Clinton allowed Taiwan President Lee Teng-hui to make an unofficial, private visit to the US in June. Beijing added to bilateral tensions with the arrest of Mr Wu on June 19, charging him with espionage. Mr Tarnoff is also expected to discuss the possibility of a summit in October between Mr Clinton and Chinese President Jiang Zemin, although Mr Christopher said two weeks ago that it would be hard to imagine holding such a meeting if Mr Wu were still incarcerated. Mr Jiang is due in New York in October for a UN summit celebrating the world organisation's 50th anniversary. The US has suggested Mr Jiang and Mr Clinton could hold bilateral talks either in New York or Washington. The State Department said Mr Tarnoff might also raise the issue of two American defence attaches from the Hong Kong consulate who were detained recently and expelled from China for alleged spying. While in Shanghai, Mr Tarnoff will meet American businessmen.
