US economic strategy against Iran faces challenge from China

The United States is launching a new economic strategy, termed ‘Operation Economic Outcast,’ aimed at severing all remaining financial lifelines to the Iranian government. This move follows previous military actions that failed to force the surrender of Iran’s enriched uranium stockpiles or trigger a regime collapse.

This strategy faces a significant obstacle in China, which purchases approximately 90% of Iran’s oil exports. These sales provide Tehran with tens of billions of dollars annually, essential for its state budget and military activities. For instance, in September 2025, Iran’s oil exports were estimated at roughly 63.8 million barrels, generating between $3.9 billion and $4.2 billion in gross revenue.

Washington faces a strategic dilemma: it must either exert direct pressure on Beijing—potentially opening a dangerous new front with the world’s second-largest economy—or implement limited measures that may fail to significantly reduce Iran’s petroleum revenues. Furthermore, any major disruption to global oil flows could impact international energy prices and affect American consumers.
