Wang Yi, China's Foreign Minister, publicly endorsed Pakistan's mediatory role in US-Iran dialogue on 13 May 2026, the day before the Trump-Xi summit opens in Beijing1. The endorsement followed a 12 May call between Wang and Pakistani Foreign Minister Ishaq Dar that covered Hormuz mediation and safe passage. The Pakistan channel has been the primary US-Iran mediator since the early weeks of the war; Iran missed the 9 May deadline for its reply on the US 7-point MOU, and no new written text has crossed the wire since.
By placing the endorsement on the record on 13 May, Xi Jinping has told the region the channel stays in Islamabad before Trump's wheels touch down on 14 May. That forecloses the bilateral handoff a US side might have hoped to extract: Trump arrives not to receive the channel from Xi, but to find that Xi has already published the architecture in advance. Wang Yi's readout with Dar paired Hormuz mediation with safe passage, the two operational dossiers Beijing wants kept inside the Pakistan track rather than transferred onto the Sino-American bilateral.
MOFCOM's 2 May Blocking Rules activation remains live alongside the mediation endorsement, legally barring five named Chinese refineries from complying with OFAC's Iran programme, which now includes the 11 May Hong Kong designations . Beijing is preserving the legal counter-architecture and the mediation channel simultaneously. For the negotiation architecture going into the 14-15 May summit, that means Trump arrives with 15,000 personnel in the strait but no Chinese willingness to redirect the diplomatic text, despite officials trailing Iran as a formal agenda item.
