in various aspects, so we have seen remarkable growth in their economic and political exchanges since the new millennium. The relations between China and the countries of the Gulf region have tended to develop politically and economically. China has not developed unilateral relations among the countries bordering the Arabian Gulf, that is, it has not developed relations with one country or two countries of the Arabian Gulf, but to all Gulf countries. This problem and hypothesis lead us to adopt a scientific approach to dealing with the content of the research, and we adopted here the analytical approach to verify the validity of the hypothesis adopted. As for the mutual investment between the two sides, it is clear that there is Chinese activity to expand Chinese investments in this region. China invested about $2 billion in the Gulf Cooperation Council (GCC) countries in 2005, and the volume of investments is expanding annually to reach about $40 billion in activities and fields, such as economic development. While the volume of Chinese investment in Iran reached about $11 billion in 2017, Iran is the first country in which China invested in early 2000 when it invested about $2 billion, and then expanded its investments later, taking advantage of the withdrawal of Western companies from the market Iran GCC investments in China widened after 2001 due to fears of protecting Gulf assets in Western countries and in the United States in particular. Gulf investors began pumping $1.3 billion in 2002. The volume of investments in the GCC countries in China reached about $39.2 billion in 2017.
