China Warns US of Retaliation Over Expanded Iran Sanctions Ahead of Trump-Xi Summit
REL_TIME: 26 Aug 2026 10:43Z · LANG: EN
Following the US announcement of 'Operation Economic Outcast'—a sweeping new package of sanctions targeting 60 entities, individuals, and vessels connected to Iran—China has strongly condemned the unilateral measures as illegal under international law. Chinese Foreign Ministry spokesperson Lin Jian warned that Beijing would take 'all necessary measures' to protect its economic interests, raising the prospect of retaliation through its control over critical mineral supply chains. The escalating tension comes just weeks before a highly anticipated summit between US President Donald Trump and Chinese President Xi Jinping in Washington, D.C., scheduled for September 24, 2026.
// Background
The US-Israel war against Iran, which began nearly six months prior to August 2026, has severely disrupted global energy markets and shipping through the Strait of Hormuz, where daily traffic plummeted from 20 million barrels to 5 million barrels. China has historically been Iran's primary economic lifeline, purchasing up to 95% of its crude oil through a 'shadow fleet' and independent 'teapot' refiners. Despite the conflict, China and the US have sought to maintain a fragile trade truce, with a highly choreographed state visit by President Xi Jinping to Washington planned for late September 2026.
// Key Developments
- US Treasury Secretary Scott Bessent announced 'the toughest sanctions in history' against Iran, warning that violating countries could be excluded from the dollar-based financial system.
- China, which historically purchased up to 95% of Iran's crude oil, warned the US of retaliation, emphasizing its opposition to unilateral sanctions without UN Security Council authorization.
- The US sanctions package targets 60 entities, including some in mainland China and Hong Kong, but stops short of penalizing major Chinese banks.
- Beijing holds significant leverage in the dispute due to its dominance over the global supply of critical and rare-earth minerals used by US tech industries.
- Diplomatic efforts continue in parallel, with Pakistani Army Chief Asim Munir visiting Tehran to meet top Iranian officials and prevent further escalation.
