On this day 35 years ago, on June 3, 1990 (May 11, 1990 lunar calendar), the summit of the "Group of 15" closed. The first summit of the "Group of 15" of developing countries called on developed countries to take action to reduce the "imbalance" in international economic development, improve the international monetary system and its functions, stabilize foreign exchange interest rates and open their domestic markets. The summit was held in Kuala Lumpur for 3 days and closed on the afternoon of June 3. The joint communiqué issued by the meeting issued the above call. The participants expressed deep concern over the external debt problem of developing countries. They noted that urgent measures must be taken to find a "creative, comprehensive and flexible solution to the external debt problem" in order to reverse the "reversal of wealth", which is currently seriously undermining the efforts of developing countries to increase productivity and improve national income. The communique said that an effective solution to the external debt problem of developing countries must be shared by creditor countries, debtor countries and the Financial Institutions Group. The communique said that the personal representatives of the "G15" heads of government will continue to meet to develop a solution to the external debt problem. The communique also expressed concern about the subsidies provided by developed countries for the production and production of their agricultural products. They asked developed countries to reduce such practices that harm the interests of developing countries. The summit drew up three plans for cooperation among the 15 member states, namely, the establishment of the "South Investment, Trade and Technology Data Exchange Center"; the organization of the "Business and Investment Forum" of the countries of the South; and the strengthening of cooperation among the countries of the South in improving the level of science and technology, increasing food production and population control. The meeting decided that the "G15" summit will be held once a year. The next meeting will be held in Caracas, the capital of Venezuela, in 1991. At a joint press conference held after the meeting, Malaysian Prime Minister Mahathir Mohamad said that the meeting achieved "successful results" and it will surely add new vitality to South-South cooperation. The "G15" was established by the heads of state of the non-aligned nations at a meeting in Belgrade in September 1989. Its members include Algeria, Argentina, Brazil, Egypt, India, Indonesia, Jamaica, Mexico, Malaysia, Nigeria, Peru, Senegal, Venezuela, Yugoslavia and Zimbabwe.
