- Bessent’s “economic D-Day” unveiled dozens of new Iran sanctions and threatened secondary sanctions against companies and countries continuing to do business with Tehran — but the structural problem is that China buys roughly 90% of Iran’s remaining oil exports, meaning any campaign that genuinely chokes Iranian revenue must target Chinese actors, while China’s Foreign Ministry immediately warned it will “take all necessary measures to firmly safeguard its own interests.”
- Bessent explicitly deflected when asked about targeting China directly, saying he preferred “quiet diplomacy” and “we’re not going to name names” — a posture that Craig Singleton of the Foundation for Defense of Democracies said “risks reinforcing Beijing’s view that Washington is reluctant to impose serious costs on major Chinese actors,” and that many analysts view as a continuation of the Trump administration’s pattern of threatening secondary sanctions against China without following through.
- Targeting a major Chinese bank — the most impactful lever available — would be viewed by Beijing “not only as destabilizing and insulting, but also as a breach of” the existing US-China trade truce per Hudson Institute’s Michael Sobolik, potentially triggering Chinese retaliation including export restrictions on critical minerals or limiting pharmaceutical exports to the US — with Trump and Xi set to meet in September, making a bank designation before that summit politically costly.
- The Russia sanctions precedent is instructive and cautionary: a coalition of 30+ countries froze Russian assets and cut banks off from SWIFT, yet failed to cripple Russia’s economy as trade redirected toward China and India — with Johns Hopkins professor Vali Nasr warning that broad secondary sanctions on Iran’s enablers means “the US is essentially expanding its war in the Gulf to a much greater war between itself and other global actors around the world.”
What Happened?
Bessent held a high-profile press conference Monday announcing an “economic onslaught against Iran’s financial connections around the globe,” unveiling dozens of new designations on entities, individuals, and vessels while threatening secondary sanctions against any country or company continuing business with Tehran. China responded Tuesday through Foreign Ministry spokesman Lin Jian, who stated that “China’s cooperation with Iran has always been conducted within the international framework and should not be interfered with or undermined.” The move represents a strategic pivot: with the Iran war proving politically costly and military pressure having limited oil exports without ending the conflict, the administration is betting economic strangulation can succeed while simultaneously trying to avoid the blowback that aggressive Chinese sanctions would generate — particularly ahead of the September Trump-Xi summit.
Why It Matters?
The campaign’s effectiveness is almost entirely contingent on China’s behavior. China buys ~90% of Iran’s remaining oil exports, routed through “teapot” private refiners using workarounds that China’s state sector officially avoids to preserve US financial system access. A sanctions campaign that excludes Chinese actors cannot substantially reduce Iranian revenues. But targeting major Chinese banks would be the most significant US-China economic confrontation since the tariff wars of Trump’s first term, with consequences for the trade truce, September summit, and global supply chains extending well beyond Iran. Bessent himself acknowledged the bind: “Why would I want to blow up the global financial system?” — an implicit admission that the most effective Iran sanctions tools are ones the administration is reluctant to deploy.
What’s Next?
The administration has said it will give countries and companies time to “remedy bad behavior” before imposing penalties — a grace period whose duration and enforcement seriousness determines whether the campaign has real teeth. The September Trump-Xi summit is the primary near-term constraint on escalation. After the summit, the calculus changes. Oil markets, with crude around $82.50, will be sensitive to any signal the administration is moving from threats to enforcement against the Chinese buyers who are Iran’s primary revenue lifeline.
