US President Donald Trump warned Chinese President Xi Jinping during a closed-door meeting at the White House on Thursday, September 24, 2026, that any direct or indirect aid from Beijing to Iran is completely unacceptable. According to US Ambassador to China David Perdue, Washington received assurances from Beijing during the talks that China is not supplying such support, despite ongoing concerns over potential indirect military and economic assistance.
US-China White House Talks Center on Iran
President Trump and President Xi met privately in the Oval Office on Thursday, September 24, 2026, to discuss major geopolitical tensions, including the ongoing conflict involving Iran. While Trump offered limited specifics to reporters regarding the discussion, stating simply, “Iya, kami membahasnya” when asked about Iran, Ambassador Perdue provided broader context in subsequent media interviews.
Speaking to CNBC on Friday, September 25, 2026, Perdue emphasized that Washington had previously made its position clear to Beijing weeks prior to the summit. Perdue stated that any assistance provided to Tehran—whether intelligence, spare parts, or military equipment—crosses a red line for the United States. Concurrently, VIVA reporting notes that the discussions took place against the backdrop of earlier US and Israel military actions against Iran.
Weighing Direct Warnings Against Beijing’s Assurances
Washington has remained vigilant regarding indirect support channels. According to statements made by Perdue to CNBC, the US government holds no direct evidence that Beijing is actively helping Tehran maintain the closure of the strategic Strait of Hormuz. However, US officials maintain suspicions about indirect backing.
Contrasting these US concerns, VIVA reported that a senior Iranian official stated on Friday, September 25, 2026, that Chinese officials assured Tehran that Beijing would not restrict economic, political, or military relations with Iran despite pressure from Washington. Meanwhile, Perdue told Fox News on Saturday, September 26, 2026, that the US received direct commitments from Beijing during the Thursday meetings, noting that US officials have already observed signs that China is heeding the warnings and halting certain activities.
Did you know? Reuters reported in July that Iran was expected to receive up to 400 shoulder-fired, Chinese-built air defense missile launchers. Sources also indicated that Tehran has utilized barter-like trading schemes to evade oil sanctions while acquiring billions in Chinese goods and military equipment.
Strategic Alignment on Nuclear Weapons and Maritime Security
Trump and Xi reportedly agreed that Iran must not acquire nuclear weapons and that the Strait of Hormuz must remain open to international shipping, a development Perdue characterized as significant progress.

The Thursday summit also featured a state dinner at the White House. Trump remarked that bilateral relations between Washington and Beijing “belum pernah sebaik ini” (have never been better), while acknowledging that the two nations represent different systems. President Xi described the talks as a sincere and profound exchange of views that provides a new strategic direction for US-China relations.
