Iranian ambassador to China Abdolreza Rahmani-Fazli wrote Monday on X that relations between Tehran and Beijing “are stronger than any US effort aimed at changing China’s position toward Iran through pressure.”
Chinese Foreign Ministry spokesman Guo Jiakun reinforced that message Monday, saying Beijing’s position remained “clear and consistent” and that the priority should be preventing renewed war and further escalation.
Crucially, Beijing also signaled opposition to any US-led blockade of the Strait of Hormuz, saying such actions were “not in the common interests of the international community.”
Observers viewed last week’s meeting in Beijing between Iranian Foreign Minister Abbas Araghchi and Chinese Foreign Minister Wang Yi as an effort to coordinate positions ahead of the expected Trump-Xi talks.
During the meeting, Wang said China was prepared to play a “greater role” in regional peace efforts and encouraged dialogue between Iran and Persian Gulf Arab states.
Trump pressure Xi over Iran
Western media reports indicate Trump plans to press Xi over China’s economic and strategic ties with Iran, particularly oil purchases and alleged military assistance.
While Trump acknowledged he would raise the issue, he also said before departing for Beijing that he did not believe Xi’s cooperation was strictly necessary to manage the crisis.
Tensions between Washington and Beijing over Iran have intensified in recent weeks following the seizure of a Tehran-linked cargo vessel near the Strait of Hormuz.
In a CNBC interview, Trump criticized what he described as China’s “unexpected support for Iran,” saying he had anticipated greater understanding from Beijing.
Former US ambassador Nikki Haley also alleged on X that the seized vessel was carrying chemicals intended for Iran’s missile program, presenting the case as evidence of growing Chinese support for Tehran.
China’s expanding regional role
At a May 8 press conference in Beijing, Rahmani-Fazli said Tehran and Beijing had agreed to advance Xi’s four-point regional security initiative.
The proposal emphasizes peaceful coexistence, respect for sovereignty and territorial integrity and adherence to international law as foundations for stability in the Persian Gulf and the broader Middle East.
Iranian outlet Khabar Online described the initiative as part of Beijing’s broader effort to position itself as a major diplomatic mediator in the region while distancing itself from what it called US unilateralism.
The outlet argued that the approach could strengthen Iran’s negotiating position and increase pressure on Washington to accept at least some Iranian demands.
Rahmani-Fazli said Monday that any future agreement with Washington “must inevitably include guarantees from major powers” and ultimately be raised at the UN Security Council.
Could China become a mediator?
So far, China has largely pursued a cautious approach to the confrontation between Iran and the United States, avoiding direct involvement while calling for de-escalation.
Still, some Iranian analysts believe Beijing may now be willing to take on a more active diplomatic role.
Former Iranian ambassador to China Mohammad Keshavarzzadeh told Shargh newspaper that Chinese officials appeared interested in facilitating negotiations and reducing tensions.
Iranian Foreign Ministry spokesman Esmail Baghaei also suggested Beijing could use Trump’s visit to warn against what Tehran describes as unlawful US pressure and its consequences for regional and global stability.
At the same time, some Iranian analysts believe China may be uneasy with Tehran’s threats to restrict access through the Strait of Hormuz.
Former Iranian diplomat Kourosh Ahmadi told Nour News that Beijing’s primary concern remains preserving open trade routes essential to its export-driven economy.
According to Ahmadi, this could push China to place greater emphasis on protecting the legal status of international waterways and opposing any disruption in Hormuz that might set precedents elsewhere.
Disputes over Chinese support for Iran
Last month, Trump called on Xi not to send weapons to Tehran and claimed China had offered assurances on the matter.
In recent days, the US State Department sanctioned three Chinese satellite companies accused of assisting Iranian military operations by providing imagery linked to Iranian military activity. Beijing rejected the allegations.
The US Treasury Department also sanctioned several companies in mainland China and Hong Kong accused of helping supply weapons-related materials to Iran.
Beijing does not recognize US sanctions on Iranian oil exports and has instructed domestic companies not to comply with American restrictions targeting so-called “teapot” refineries purchasing Iranian crude.
The moves underscore growing US efforts to pressure Beijing over its ties with Tehran ahead of the Trump-Xi meeting.
