To advance a broad investment program in Iran, Beijing`s growing impatience with the Trump administration after its withdrawal from the nuclear deal appears to be a signal. China has repeatedly called on the government to maintain the agreement it belongs to and has strongly condemned the United States` application of unilateral sanctions. After more than seven years in power, the Rohani government is facing some successes, and the Sino-Iranian agreement could be a way for them to tell their people to wait a little more simply because things are getting better. And things could be better in Iran, as the leaked information shows that one of the terms of the agreement provides for a Chinese investment of nearly $400 billion in the oil, gas and petrochemical industry in Iran. Nevertheless, the agreement is so controversial that even some politicians and Iranian government media have criticized it. For example, a headline in the Arman Melli newspaper states that Iran is not Sri Lanka, while an article in the daily Hamdeli asked every day whether Iran would become a Chinese colony. Most importantly, the rivalry between the United States, Iran`s main adversary, and China, Iran`s main supporter, played a key role in signing the agreement. The trade war between the United States and Sino is long-lasting and this agreement is a new choice in the fight between the two. It would not only allow Iran to avoid sanctions, but also a serious challenge to U.S. supremacy in the Middle East.
China would undermine its stated goal of promoting stability and peace by opposing U.S. sanctions and doing business with Iran, and would also send a clear message to all other countries that may be in trouble. On the basis of this agreement, China has agreed to invest between $280 billion and $400 billion in Iran`s oil, gas and petrochemical industries through foreign direct investment.  China`s growing influence in East Asia and Africa has called into question U.S. interests, and the Middle East is the next battleground on which Beijing can challenge American hegemony, this time by Iran. This is all the more important because the agreement and its implications go beyond the economic field and bilateral relations: it operates at the internal, regional and global levels.
