Riyadh turned to China for help after the Houthis made rapid advances along the Red Sea coast and around the Bab el-Mandeb Strait, moves that have left Saudi oil exports and shipping more exposed, the sources said.
China has publicly called for restraint, dialogue and the restoration of safe navigation, but its private message went further than the public statements, they said.
Beijing wants Iran to use its influence with the Houthis to help prevent the conflict spreading further across energy routes on which China, the world’s second-largest economy, depends.
The sources, who were briefed on the discussions and spoke on condition of anonymity, did not provide details of how the message was delivered or whether it was conveyed during a visit to China on Wednesday by Iranian Foreign Minister Abbas Araqchi.
The sources said Tehran’s response was that stability and peace in the region depend on ending the US-Israeli war on Iran.
Chinese officials did not issue any explicit threats or indicate that Beijing would seek to pressure Tehran economically if it failed to use its influence over the Houthis, the three Iranian sources said.
In response to a Reuters request for comment on this story, the Chinese foreign ministry said: “China does not wish to see regional tensions further spill over into Yemen and the Red Sea. Escalating regional instability is not in the interests of any party”.
“The sovereignty and security of all countries should be respected, and facilities vital to people’s livelihoods must not be targeted. China calls for an end to actions that further complicate the situation and urges resolving issues through dialogue and negotiation,” it said.
Iran’s foreign ministry and the Saudi government’s media office did not immediately respond to Reuters requests for comment for this article.
DANGERS OF A WIDER REGIONAL WAR
China has been Iran’s largest trading partner for more than a decade and remains the main buyer of its oil. Chinese purchases accounted for more than 80% of Iran’s seaborne oil exports in 2025, averaging about 1.4 million barrels per day, according to commodities data and analytics firm Kpler.
“Beijing is one of the few capitals that can still press Iran to rein in the Houthis,” said a senior Western diplomat in the region.
The Houthis, who emerged in the 1990s in opposition to Saudi Arabia’s Sunni religious influence in Yemen, are armed, trained and funded by Iran, according to Iranian sources and Western countries, and form part of Tehran’s anti-Western, anti-Israel “Axis of Resistance”.
Any threat by the Houthis to shipping in the Red Sea and through the Bab el-Mandeb Strait risks sharply worsening the global energy crisis since Iran started blocking the Strait of Hormuz and increasing the danger of a wider regional conflict.
With Hormuz already effectively shut, sustained Houthi attacks on vessels or ports in the Red Sea would disrupt the Middle East’s two main oil-export routes simultaneously, opening a new front in both the energy crisis and Iran’s broader confrontation with the United States.
Iran and its allies now exert pressure over both ends of the region’s key maritime network, one of the sources said, adding that “China depends on both”.
Alex Vatanka, director of the Iran Program at the Middle East Institute in Washington, said Beijing may oppose US pressure on Tehran, but its interests in the Middle East extend well beyond Iran. Roughly half of China’s oil imports come from the region, while trade between China and the Gulf Cooperation Council states totals around $300 billion a year.
“Iran can disrupt Hormuz. But at some point that leverage begins hurting the very power Tehran increasingly depends on,” Vatanka said.
CHINA’S DILEMMA
It is unclear whether Tehran will act on the concerns raised by Beijing, according to the three Iranian sources.
The relationship nevertheless carries significant economic and strategic weight for Iran as it continues to face hostilities with the US, they said.
China is among the few countries with the financial capacity to provide the investment Tehran needs to sustain its oil industry and ease pressure on its economy, battered by war and sanctions.
Beijing has also demonstrated its diplomatic influence. In 2023, China brokered the agreement that restored ties between Iran and Saudi Arabia after years of hostility.
