CHINESE President Jiang Zemin had a 40-minute 'constructive' talk with US Vice-President Al Gore yesterday despite an aborted summit with President Bill Clinton. Asked if the achievement of the talks could be compared to the originally planned summit, Foreign Ministry spokesman Chen Jian said one of the differences was that one hour had been set aside for the meeting with Mr Clinton, 20 minutes longer than yesterday's one. But Mr Chen said the meeting was still 'positive, beneficial and constructive'. Mr Gore had conveyed Mr Clinton's views on the development of Sino-US relations and emphasised the US policy towards China was one of engagement, not confrontation, said Mr Chen. Mr Jiang had urged the US to reduce troubles and minimise confrontation, the spokesman said. Mr Jiang also emphasised that, as regards Taiwan, the US should be wary of 'manipulation'. Mr Gore is said to have reiterated that the US would abide by the one-China policy. On non-proliferation, Mr Gore put forward a proposal and Mr Jiang said China was ready to consider it, said Mr Chen. Mr Gore also expressed Mr Clinton's hope to have mainland Defence Minister General Chi Haotian visit the US. General Chi called off a scheduled visit to the US last June in protest at a visit by the Taiwan President Lee Teng-hui. Mr Chen said no date had been fixed for the next Sino-US summit. Mr Gore is to meet Japanese Prime Minister Tomiichi Murayama, and leaders from Thailand and South Korea today after the conclusion of the APEC summit.
