US warns allies, China to back economic war on Iran

Six months into a deeply unpopular U.S. military engagement in Iran, the White House has announced a dramatic strategic shift, launching what it calls the most sweeping coordinated economic isolation campaign in modern history to topple the Tehran government. U.S. Treasury Secretary Scott Bessent outlined the new initiative to reporters at the White House on August 20, 2026, framing the economic push as an alternative to expanding costly large-scale military operations that have faced mounting domestic backlash ahead of critical midterm elections.

Speaking to CNBC, Bessent confirmed that the administration is demanding full participation from both U.S. allies and major competing powers including China, issuing a stark “you are either with us or against us” ultimatum to the global community. When pressed about how Washington will compel Beijing to align with the campaign, Bessent declined to share public details, noting that sensitive discussions are often held privately, but explicitly called on China to “get with the program.” The issue of Iran is set to be a top agenda item when Chinese President Xi Jinping visits the White House on September 1, a follow-up to the Iran discussions that took place during Trump’s May summit in Beijing.

Bessent emphasized that the ramped-up economic pressure is intended to reduce the likelihood of resuming large-scale kinetic military action against Iran, though he stopped short of ruling out future military deployments. “If we are doing the maximum economic pressure, then that means that likely there will not be a large-scale kinetic restart, but I will emphasize that is for now,” he said, adding that full details of the new sanctions and enforcement measures will be released during a formal press conference scheduled for Monday.

Iran has swiftly rejected the new campaign, dismissing it as a cynical distraction from growing economic troubles facing the United States. Iranian Foreign Minister Abbas Araghchi took to X to point out that the so-called “Economic D-Day” comes as the U.S. grapples with unprecedented national debt and soaring interest costs, while the Iranian foreign ministry labeled the new sanctions threats a clear act of “economic terrorism.”

The strategic shift comes amid a months-long military stalemate following the U.S. and Israeli launch of military operations against Iran on February 28. Currently, Tehran maintains partial closure of the strategic Strait of Hormuz, while the U.S. enforces a naval counter-blockade of Iranian trade. After six months of combat, the U.S. has failed to force Iran to abandon its enriched uranium program or its stated plans for civilian nuclear energy, a core demand of the Trump administration, which has insisted it will not allow Iran to develop a nuclear weapon.

Domestic criticism of the administration’s war handling has intensified in recent weeks, after reports of abysmal living conditions aboard the USS Abraham Lincoln, which has been deployed to the Middle East since November 2025. The vessel reportedly faced widespread food shortages, broken plumbing systems, and multiple suicide attempts among crew, prompting the Pentagon to replace it with the newly arrived USS George Washington carrier strike group, which arrived in the region Wednesday.

This new economic campaign is not the first time Trump has prioritized economic pressure against Iran. During his first term from 2017 to 2021, Trump withdrew from the landmark nuclear deal negotiated by former President Barack Obama and implemented a harsh “maximum pressure” sanctions regime. Despite decades of sweeping U.S. sanctions and the earlier maximum pressure campaign, Iran has managed to continue exporting oil largely via a shadow fleet of sanctioned tankers, with China remaining its largest crude oil customer. In his initial announcement of the new campaign on Truth Social, Trump called for an immediate end to all activities that facilitate Iranian oil trade, including what he termed “oil smuggling, swap lines, cash transfers, exchange houses, ship registries, front companies,” though he did not name any specific countries aiding Iran in these activities.
