In the field of diplomatic work, the resolution "makes it clear that diplomacy with Chinese characteristics should serve national rejuvenation, promote human progress, promote the construction of a new type of international relations and build a community with a shared future for mankind", which points out the right direction and provides a fundamental basis for us to do a good job in diplomacy in the new era. In today's world, the changes of the century and the epidemic situation of the century are intertwined and superimposed. With the deepening of world multipolarization, economic globalization, social informatization and cultural diversity, the reform of the global governance system and the international order has accelerated, and the interdependence of countries around the world has deepened. Peace and development remain the theme of the times. At the same time, the international community is also faced with one after another instability and uncertainty. Economic globalization has encountered a countercurrent. Unilateralism, protectionism, hegemonism, cold war thinking and group politics are posing a new threat to the peace and development of all mankind. In the face of profound changes in the world order and the international environment, China's diplomacy must create a new situation in line with its historical positioning and the responsibility of the times. Since the 18th CPC National Congress, socialism with Chinese characteristics has entered a new era, and China is increasingly approaching the center of the world stage.

A key embodiment of diplomacy for the people is to create a peaceful and stable external environment for domestic economic construction. This is not only reflected in maintaining world peace and promoting common development, but also in maintaining good neighborly and friendly peripheral relations. It also needs to create and maintain an open and inclusive cooperation environment, a stable and orderly security environment and an objective and friendly public opinion environment for China all over the world. In addition, China's diplomacy should also be further promoted in establishing and improving the protection mechanism for overseas citizens and enterprises, responding quickly and efficiently to the actual needs of local citizens and overseas Chinese, safeguarding the legitimate rights and interests of overseas Chinese and promoting non-governmental exchanges. At the same time, diplomacy for the people is also reflected in China's diplomacy to promote the common progress of all mankind. China should always be a builder of world peace, a contributor to global development and a defender of the international order. In fact, the Communist Party of China has always been willing to benefit the people of all countries in the world and strive for the cause of human progress. It has always been committed to promoting mutual understanding, support and help among the people of all countries and jointly promoting the noble cause of world peace and development. This progressiveness essentially determines the global vision, world vision and historical mission of the diplomacy of major countries with Chinese characteristics in the new era.
