The State Visit of Chinese President Jiang Zemin in October 1997 represented a thaw in official Sino-US Relations, which have been somewhat chilly since Tiananmen in 1989. Despite reaching agreements on a broad range of security, economic, environmental and law-enforcement issues, the two Presidents were clearly far apart on the issue of human rights. While President Clinton made mention of the right to political and religious expression, President Jiang expressed the need for political and social stability in his country. On the whole, both leaders have achieved their goals. President Clinton has secured China's cooperation on several issues, most importantly arms control and trade, while the state dinner and formal ceremony recognized China's role as a key player in the world economy and Jiang's international position as its head of state.
