As the war between the United States, Israel, and Iran rages on in the Middle East, the world’s attention has shifted to Beijing, where China’s diplomatic maneuvers—and its shadowy role in the conflict—have come under intense scrutiny. Since the outbreak of hostilities on February 28, 2026, American intelligence agencies have sounded the alarm about a potentially widening conflict, as both Russia and China appear to be weighing support for Iran, raising the stakes for global security and energy markets.
According to CBS News, just days after the war began, analysts at the Defense Intelligence Agency detected signs that China was considering providing Iran with advanced X-band radar systems. These sophisticated systems could dramatically bolster Iran’s ability to detect and track incoming threats, such as low-flying drones and cruise missiles, making it harder for U.S. and Israeli forces to strike Iranian targets with impunity. While it remains unclear whether China ultimately moved forward with this transfer, the mere possibility has fueled deep concern in Washington that the conflict is drawing in not only regional adversaries but also global powers eager to counterbalance U.S. influence.
The specter of foreign involvement doesn’t end with China. U.S. officials also told CBS News that Russia has shared intelligence with Iran about American military positions across the Middle East. This alignment among U.S. rivals—short of direct military intervention but potentially game-changing—has left American policymakers on edge. The Defense Intelligence Agency and the Central Intelligence Agency have both declined to comment on these developments, while the White House remains silent.
Meanwhile, the technological chess match is playing out not just on the battlefield but in orbit. As reported by the Financial Times and corroborated by U.S. officials, Iran’s Islamic Revolutionary Guard Corps (IRGC) used a spy satellite secretly purchased from the Chinese company Earth Eye Co. to target U.S. bases in the region. While it’s unclear if the satellite imagery used in recent operations was supplied directly by Earth Eye Co., the Pentagon’s own report released in December 2025 warned that Chinese commercial satellite firms have exchanged technology and data with the IRGC. The 2026 Annual Threat Assessment, an unclassified review of global security risks, went further, stating, “China has eclipsed Russia as the key U.S. competitor in space. Beijing’s rapid deployment of space capabilities positions it to use space to advance its foreign policy goals, challenge U.S. military and technological superiority in space, and project power on a global scale.”
China’s support for Iran, however, appears to be more nuanced than simple military assistance. U.S. intelligence also suggests Beijing has considered sending air defense systems and shoulder-fired anti-air missiles (MANPADs) to Tehran, potentially routed through third countries to mask direct involvement. CNN reported last week that China was preparing to deliver these MANPADs. Democratic Senator Mark Warner, vice chairman of the Senate Intelligence Committee, didn’t mince words when he called the potential Chinese arms transfers “significant” during an April 12 appearance on CBS’s “Face the Nation.” Warner added, “They try to hide themselves. China says, well, this is their private sector. We all know there is no such thing as a true private sector in China. Every company in China has to have its first loyalty to the Communist Party.”
Former President Donald Trump, who is set to visit China for a high-stakes summit with President Xi Jinping on May 14 and 15, has taken a characteristically combative approach. In an interview aired April 15 on Fox Business Network, Trump claimed he sent a letter to Xi asking him not to supply weapons to Iran and threatened an immediate 50% tariff on any country caught doing so. The Chinese Embassy in Washington, D.C., responded by denying the allegations, with spokesperson Liu Pengyu stating, “We uphold an objective and impartial stance and have made efforts to promote peace talks. We never engage in actions that escalate conflicts.” China’s foreign ministry went a step further, calling reports of Beijing supplying Tehran with weapons “purely fabricated” and warning that any Trump-imposed tariffs would be met with countermeasures.
Despite these denials, China’s role in the Iran war is anything but passive. As NDTV reported, Beijing is accelerating diplomatic efforts to end the conflict, walking a delicate line between supporting its longtime partner Tehran and preparing for the upcoming summit with Trump. President Xi’s approach is shaped as much by China’s economic interests—half of its crude oil imports come from the Middle East—as by the desire to avoid alienating either side. Trump himself credited China for helping bring Iran to peace talks in Pakistan on April 11, a claim echoed by Eric Olander, editor-in-chief of the China-Global South Project. “That puts them in the room with negotiators, even if it’s not a seat at the table,” Olander observed.
Xi Jinping broke his silence on the crisis on April 14, unveiling a four-point peace plan that calls for “upholding peaceful coexistence, national sovereignty, the international rule of law and balancing development and security.” Chinese Foreign Minister Wang Yi has been busy, holding nearly 30 calls and meetings with counterparts in a bid for a ceasefire. Special envoy Zhai Jun has toured five Gulf and Arab capitals, sometimes traveling by road to avoid contested airspace, and heard air-raid sirens firsthand, according to Reuters. Xi’s peace plan was announced during a meeting with Abu Dhabi’s crown prince, as China sought to deepen ties with regional players while gently nudging Iran toward dialogue.
Yet, for all this activity, many analysts see China’s Middle East diplomacy as more theatre than substance. Patricia Kim of the Brookings Institution told Reuters, “While the Iranians are keen to play up their relationship with China and have asked Beijing to serve as a guarantor of a ceasefire, Beijing has shown zero interest in assuming such a role. Beijing appears content to remain on the sidelines as the United States bears the brunt of the pressure.” Drew Thompson, a senior fellow at Singapore’s S. Rajaratnam School of International Studies, put it bluntly: “Beijing’s ideal outcome is the maintenance of no-strings-attached relationships with anti-Western countries like Iran but also preserving its opportunity to achieve some form of modus vivendi with the US.”
China’s own foreign policy doctrine of non-interference is being tested. Despite being Iran’s largest trading partner, Beijing has refrained from using its economic leverage to pressure Tehran, and has been noncommittal about guaranteeing Iran’s security. Ding Long, a professor at the Middle East Studies Institute of Shanghai International Studies University, told The New York Times, “Helping the United States or Israel is not China’s intention because China opposed this war from the very beginning.” Xi Jinping, during meetings with the crown prince of Abu Dhabi and the prime minister of Spain, condemned the violation of international law as a “return to the law of the jungle”—a veiled dig at Trump’s strategy—but offered little more than a call for respect for sovereignty and international law.
With the U.S. blockade of Iranian ports and a global energy crisis looming, all eyes are on the upcoming Trump-Xi summit. While some hope for a grand bargain, most experts expect the meeting to focus narrowly on trade and strategic stability, perhaps with a splashy deal—like a major Boeing aircraft purchase—to sweeten the headlines. As Scott Kennedy of the Center for Strategic and International Studies put it, “There is zero chance China will reach some sort of grand bargain with the United States.”
For now, China seems content to play both sides—publicly calling for peace, quietly hedging its bets, and keeping its options open as the world’s balance of power is tested once again in the Middle East.
