Sometimes the construction, integration and localization of specialized concepts from other sciences can be helpful for researchers in understanding political and international relations. In fact, one of the benefits used in the geopolitical system is the concept of connectography. Global transport, energy and communications infrastructure that facilitate the supply chain, especially in large cities by creating wide corridors of economic exchange, create a network of global civilization with complex dynamics of power.

in the present study, we intend to use the mentioned concept and in the framework of neo-regionalism theory, to examine the impact of the foreign policy of the People's Republic of China in the form of three strategies of economic diplomacy, peripheralism and petro-yuan on the foreign policy of the Islamic Republic

With the possibility of the cancellation of international sanctions and the presence of western and eastern investors in Iran, the country's authorities plan to add more than two thousand kilometers to the country's railway track annually in the next five years, which will certainly affect Iran's regional role and position. will improve even more.

The main challenge of Iran's foreign policy strategy in the region in the current situation is how to establish a kind of balance and compatibility between the two issues of strengthening "regional cooperation" and "deterring threats from the region". The solution to this issue is to design a third strategy in Iran's foreign policy, which is able to establish a kind of balance between the strategic limitations caused by the necessity of playing the role of other regional and extra-regional actors for Iran, on the one hand, and taking into account the country's existing economic resources. On the other hand, to play a continuous and expensive presence in the form of a big game.
