Another success of the League of Nations is that it can promote development by establishing international systems and rules. With the outbreak of World War II, the League of Nations exposed many problems. However, the alliance has reached some important international agreements, such as the signing of the Bandung Declaration, which is a milestone between Asian and African countries and is conducive to their unity and treaties against colonialism and inequality. The Alliance has also established the International Labour Organization and the International Unicom Alliance, which provide a platform for improving the welfare of workers around the world and promoting information and exchange. These international agreements and institutions have also established ways and means to deal with international issues, which is an important contribution of the League of Nations.
Although the League of Nations gradually ended its mission after World War II, its successful experience still provides reference for international organizations and international cooperation. The original intention and desire of the alliance-avoiding war through consultation and mediation and promoting economic development and people's well-being-once again warmed the world stage. In many global crises and wars, the alliance has provided us with a cooperative organization and demonstrated the power of cooperation and compromise. Today, we need a new international alliance to promote the universal and sustainable development of human society. This new alliance should uphold and cherish international law and multilateralism in principle, encourage global cooperation and exchanges, and provide the necessary platform for solving global challenges.
