Twenty-eight years ago today, on April 24, 1997 (March 18, 1997 lunar calendar), the border disarmament agreement between the five countries of China and Russia, Hagita, was signed. After the agreement was signed, the heads of state of the five countries clasped their hands together. On April 24, 1997, President Jiang Zemin, who was on a state visit to Russia, signed an agreement on mutual reduction of military forces in the border areas with Russian President Yeltsin, Kazakh President Nazarbayev, Kyrgyz President Akayev, and Tajik President Rakhmonov at the Kremlin. According to Shen Guofang, Director of the Information Department of the Ministry of Foreign Affairs, who accompanied President Jiang Zemin's visit, the main contents of the above-mentioned agreement are: our country and Russia, Kazakhstan, Kyrgyzstan and Tajikistan will reduce the military forces in the border areas to the minimum level compatible with good neighborliness and friendship, so that they are only defensive; do not use force or threaten each other with force, and do not seek unilateral military superiority; the military forces deployed in the border areas of the two sides will not attack each other; reduce and limit the number of personnel and main types of weapons deployed in the army, air force, air defense air force, and border defense forces on both sides of the border at a depth of 100 kilometers, and determine the maximum limit for retention after reduction; determine the method and duration of reduction; exchange relevant information on military forces in the border areas; supervise the implementation of the agreement, etc. The agreement is valid until December 31, 2020 and can be extended by mutual consent. Within 100 kilometers of each side of the 7,000-kilometer-long border line, each side will retain no more than 130,400 army, air force and air defense aviation personnel after the reduction. But this does not mean that China's troops will be transferred to other regions. There is no issue of military alliance in terms of content and purpose of this agreement. The agreement clearly stipulates that it will not target third countries and their interests. The negotiations between our country and Russia, Kazakhstan, Kyrgyzstan and Tajikistan on mutual reduction of military forces in the border areas began in November 1989, when it was held between China and the Soviet Union. The negotiation aims to implement the agreement reached by the leaders of the two countries on reducing the military forces deployed in the border areas of China and the Soviet Union to a minimum level commensurate with the normal good-neighborly relations between the two countries and maintaining tranquility in the border areas when the Sino-Soviet relations were normalized in May 1989. On April 24, 1990, the Chinese and Soviet governments signed the "Agreement on Guiding Principles for Mutual Reduction of Military Forces in the Border Areas and Strengthening Trust in the Military Field". After the disintegration of the Soviet Union in December 1991, Russia, Kazakhstan, Kyrgyzstan and Tajikistan formed a joint delegation to continue border disarmament negotiations with China. According to the "Guiding Principles Agreement", the two sides first reached an agreement on the "Agreement on Strengthening Trust in the Military Field in the Border Areas". On April 26, 1996, the heads of state of China, Russia, Kazakhstan, Kyrgyzstan and Tajikistan signed the agreement in Shanghai. In early 1997, after negotiations, the two sides completed the formulation of the Agreement on Mutual Reduction of Military Forces in Border Areas. President Jiang Zemin and President Yeltsin signed the Joint Declaration of the People's Republic of China and the Russian Federation on World Multipolarization and the Establishment of a New International Order.
