Reuters reported on Saturday, citing three diplomatic sources, that China is now in direct formal negotiations with Iran to guarantee safe passage for crude oil and Qatari LNG through the strait of Hormuz. The talks formalise what had been an improvised arrangement: Chinese-linked vessels quietly transiting the strait using AIS flag-switching while Western-flagged shipping sat at anchor after every major P&I club cancelled war risk cover.
The progression from ad hoc workaround to diplomatic negotiation followed a precise sequence. When the P&I insurance deadline passed at midnight on 5 March, more than 150 vessels were stranded in the Gulf of Oman and Arabian Sea. Trump's promised DFC insurance programme and Navy convoy escorts remain non-operational. Beijing waited for both failures — the commercial insurance collapse and the US Navy's inability to escort — before moving from quiet flag-switching, exemplified by the vessel Iron Maiden's AIS-broadcast transit, to formal state-to-state talks. The strategic patience of China's first week was not passivity. It was positioning.
Iran's calculus is straightforward. China is its most important remaining economic relationship and the only major power not aligned against it in this war. Refusing Chinese passage would cost Tehran its last significant ally. For Beijing, the arrangement achieves through one week of war what decades of naval expansion in the Indian Ocean could not: a legitimate, negotiated role as The Gulf's energy security guarantor. The Saudi backchannel to Iran, re-activated with 'increased urgency' through the Chinese-brokered 2023 rapprochement framework, now operates in a context where China holds material leverage over both parties.
The consequences fall hardest on countries outside the arrangement. India imports 85% of its crude by sea through waters increasingly under Chinese diplomatic management — and New Delhi has still not issued a formal protest over the sinking of IRIS Dena in waters it considers strategically important. If roughly 60% of Gulf oil flowing to Asia resumes at terms Beijing sets while the share bound for Western markets remains blocked, the result is not a blockade in the traditional sense. It is a filter — and China controls who passes through it.
