Which country needs international cooperation more, developed or developing?

International cooperation is an important form of international economic and trade cooperation that has flourished since the Second World War. Especially in the past 20 years, with the continuous development of the economies of all countries in the world and the further aggravation of the imbalance of economic development, the international division of labor has been developing in depth and breadth, and the economic dependence of all countries has been further strengthened. As an extensive, regular and effective way of economic cooperation, international cooperation has been paid more and more attention by all countries, and its development speed has exceeded the growth rate of trade in goods. According to rough statistics, the world labor trade doubled from 1960 to 1970, and doubled from 1970 to 1975. At the end of 1970s, there were about 20 million temporary international migrant workers in the world, of whom120,000 were from developing countries. At present, the total world trade in services has exceeded 1 trillion dollars, accounting for about one-third of the total world trade in goods. Labor service is the abbreviation of labor service, which refers to the living labor provided by the labor owner to the unit or individual who needs this kind of labor service. This kind of living labor can be productive labor in industries such as industry and agriculture, or service labor in industries such as commerce, tourism, finance, insurance, transportation, communication, construction, medical care and education. This is actually a rational allocation of labor factors. International labor service cooperation, also known as labor service or labor force export, refers to the activities that all kinds of technical and ordinary labor services from one country go to another country to provide various productive or service services for government agencies, enterprises or individuals in another country and get due remuneration. In fact, it is the reorganization and allocation of labor factors in the world. There are some differences between international labor service cooperation and international service trade, because labor service cooperation is about the international movement of labor force as one of the production factors, and it is only a part of extensive international service trade. Contemporary international labor cooperation is also different from the simple labor transfer in the past. In the period of primitive capital accumulation, the transfer of labor was a compulsory slave trade, and even between the two world wars, it was also a colonial immigration activity, which was different from today's labor cooperation. Contemporary international labor service cooperation came into being after the Second World War. After years of development, it has formed a kind of labor service in the form of international project contracting, international investment, technical services and consulting services, and has become an important form of contemporary international economic cooperation. The function of international labor cooperation lies in that, as a mutually beneficial form of international economic cooperation, it not only deepens the internationalization of production, promotes the development of international trade, accelerates the international transfer of advanced science and technology, but also greatly promotes the economic development of labor exporting countries and labor importing countries. The international migration of labor has had a positive and far-reaching impact on the development of the world economy.
