Twentieth Anniversary of Establishment of Diplomatic Ties Commemorated 　　China and the United States, as the permanent members of the UN Security Council and nuclear powers, shoulder the common responsibilities in maintaining world peace and stability, and carry out efficient cooperation in handling international affairs, but still face some difficulties and challenges. 　　Li Zhaoxing, Chinese Ambassador to the United States, made the remarks at a meeting in Washington, which was commemorating the 20th anniversary of the establishment of Sino-US diplomatic relationship. 　　Li refuted the "China Threat", spread by a few Americans and pointed out that accusation of China of so-called "stealing US technology" and "cracking down on political dissidents" was groundless. 　　China and the United States are establishing constructive strategic partnership oriented toward the 21st century, Li said, adding that the healthy and smooth development of the Sino-US relationship will not only benefit the two peoples, but also the world as a whole. 　　 WorldNews 1999-01-18 Page6 Full Story in Chinese
