Scott Bessent said on Tuesday 25 August that buyers of Iranian oil face an "economic D-Day", declining to name China and adding "we know who they are"1. China's foreign ministry spokesman Lin Jian replied that sanctions "do not help" and that Beijing would "take all necessary measures to firmly safeguard its own rights and interests"2. The warning followed the Treasury Secretary's promise of unprecedented economic-isolation measures a fortnight earlier.
Chinese imports of Iranian crude had already halved before he spoke. Emma Li of Vortexa puts them at about 700,000 barrels a day, down from roughly 1.4 million before the war, driven by lower Chinese refinery runs and inventory drawdowns rather than by any sanction3. A threat aimed at a flow that commercial arithmetic has already cut delivers less than the same threat would have delivered in the spring, and Beijing can concede nothing while continuing to buy at the reduced level.
Turkey, Iraq and India all carry Iranian trade and none has signalled a cut-off. Iraq pays Iran an estimated $4bn to $5bn a year for power-generation gas, and it had already asked Tehran in August for special consideration on its own Hormuz oil exports, which is the position of a state negotiating with Iran rather than isolating it4. OPEC recorded Iranian output flat in the same period while Iraqi and Kuwaiti production surged.
Naming China would commit Washington to an instrument against Chinese refiners and banks, with a retaliation calculation attached; leaving the target unnamed keeps the warning free.
