The PRC/U.S. cooperation in high energy physics was pioneered by leaders of both countries when Mr. Deng Xiaoping visited the United States 25 years ago and signed with Mr. Carter the umbrella agreement for cooperation in science and technology between the two countries. The cooperation in high energy physics is one of the implementing accords under that umbrella agreement, which was signed by Mr. Fang Yi and Mr. Schlesinger. Since its signature, this cooperation has been smoothly and successfully carried out for a quarter of a century without suspension, during which 24 cooperative programs have been made and executed, hundreds of scientists from the five U.S. national laboratories and universities have been involved in this cooperation. The most noticeable achievement of this cooperation has been the successful completion of the Beijing Electron Positron Collider.

A very small number of the photos taken over the past 25 years has been chosen to create this modest “Photo Show”.These Photos allow us to see many familiar and dear faces, who had contributed a lot to this Cooperation. Let us remember them and wish the Cooperation pioneered by them would last.
