On Friday September 18, Senator Elissa Slotkin wrote to President Donald Trump and urged him to make China's support for Iran the centrepiece of his talks with Chinese President Xi Jinping next week. [Slotkin's letter, obtained by CBS News,](https://www.cbsnews.com/news/slotkin-xi-trump-iran-chinese-satellite-images-u-s-base-attack/?ref=diplopolis.com) said Chinese companies have been providing Iran with satellite imagery and supplying components supporting Tehran's drone and missile programmes. 'For months, we have known that Chinese companies are helping the Iranian military target and attempt to kill U.S. troops,' she wrote, calling on Trump to tell Xi this 'must stop immediately.'

[The same week, Chinese Foreign Minister Wang Yi met Iranian Foreign Minister Abbas Araghchi in Beijing.](https://www.fmprc.gov.cn/eng/wjbzhd/202609/t20260918%5F12025171.html?ref=diplopolis.com) Wang told Araghchi that China was prepared to play a constructive role in resolving international disputes, and called on Washington and Tehran to rebuild their negotiating mechanism. Araghchi said after the meeting that decisions made in consultation with China would decide the future strategic balance in the region. China was simultaneously providing the military capacity that keeps Iran fighting and offering the diplomatic framework that might end the fight. Both offers were made in the same week.

Also the same week, Saudi Aramco told at least two of its European refinery customers that they would receive no crude oil from Saudi Arabia next month. The Saudi East-West pipeline — which connects the kingdom's Gulf oil fields to its Red Sea export terminal — was struck by a drone from Iraq on September 11\. Saudi Arabia temporarily closed the pipeline. The European buyers who receive Saudi crude under standing monthly contracts will receive nothing in October. The war that began over the Strait of Hormuz has now interrupted the alternative export route that Saudi Arabia built to bypass the Strait, and the interruption is being passed directly to European fuel markets.

Xi Jinping is arriving in Washington next week for a three-day state visit — his first to the United States since 2015\. The agenda covers trade, artificial intelligence, critical minerals and the Iran war. The US-China trade deal known as the Busan Agreement is expected to be extended. Washington hopes Beijing will use its leverage as Iran's largest trading partner to pressure Tehran. Analysts say China is more likely to encourage de-escalation than apply genuine pressure. China has not stopped buying Iranian oil since the Strait of Hormuz blockade began. The US has held back from imposing secondary sanctions on Chinese entities engaged in Iran trade. The courtesy has been mutual and has not produced a deal.

The triangle is the week's most specific geopolitical fact. China provided satellite imagery helping Iran target American troops. China offered to mediate between Iran and Washington. China's president is arriving in Washington to meet the American president conducting the war that China is simultaneously supporting and offering to end. The week produced Senator Slotkin's letter, Wang Yi's constructive role offer and the Saudi pipeline disruption. None of these are separate stories. They are the same story told from four different locations.
