impact of competition between China and EU in west of Asia on national security of Iran

In West Asia, order, oil, and arms have always been the three main factors in determining the equations, which has led to the continued presence of major supra-regional powers in West Asia. Despite significant differences between China and the European Union, both are strategic partners. Given the presence of China and the European Union in the West Asian region, the question arises as to what effect the economic interests of China and the European Union in this region have on Iran's national security? The main hypothesis is: that: Since China and the European Union have no security competition and at the same time both are important economic players in the world; In the context of extensive US sanctions against Iran, the intersection of the interests of these two supra-regional powers in West Asia and its alignment with the interests of Iran's regional rivals will be a challenge to Iran's national security. This article seeks to answer the question of the article with a comparative view, based on the Copenhagen School of Security.
