China’s Defiance of U.S. Sanctions on Iranian Oil

China has instructed its companies to disregard U.S. sanctions aimed at Iranian oil, presenting a direct challenge to America’s efforts to intensify its restrictions on Iran.

A directive from China’s Ministry of Commerce was issued, referencing a “blocking law” established in 2021, which bars companies from adhering to foreign sanctions deemed unlawful. This order primarily targets several Chinese refiners that the U.S. accuses of procuring Iranian crude, especially independent refineries, often referred to as “teapot” refineries.

This step signifies a shift from years of discreet workarounds to more overt support from the state, indicating that Beijing is unwilling to align with U.S. initiatives aimed at crippling Iran’s vital revenue sources.

“It’s unprecedented. This is a significant escalation in China’s response to U.S. economic pressure. It seems to be a reaction from the Chinese government,” remarked Max Maizlisch, a senior research analyst at the Foundation for Defense of Democracies.

This escalation aligns with the heightened sanctions campaign from the Trump administration, which is targeting Chinese refiners and cautioning financial institutions about facing penalties if they enable oil trade between Iran and China.

Treasury Secretary Scott Bessent has pointed out that China’s oil purchases are supporting Iran’s economy and, by extension, funding its military endeavors.

“China, it’s time to enhance our diplomacy and persuade Iran to open the strait,” Bessent stated in a Fox News interview. He further declared, “Iran is the largest state sponsor of terrorism… China purchases 90% of Iran’s energy, which essentially funds terrorism,” he added.

China continues to be a significant market for Iranian crude, and despite escalating U.S. pressures, a large portion of Iran’s sanctioned oil exports is still funneled to Chinese refineries.

“Chinese firms are caught between obeying directives from the Chinese Communist Party or the U.S., and either choice carries serious repercussions,” Meizlisch noted.

This matter is poised to be a central discussion point in the forthcoming meeting between President Trump and Chinese President Xi Jinping.

Concurrently, diplomatic efforts are ramping up. Iranian Foreign Minister Abbas Araghchi was in Beijing for discussions with Chinese Foreign Minister Wang Yi, highlighting China’s growing influence as Iran’s leading oil buyer and a vital diplomatic partner.

Despite tightened sanctions and a U.S. naval blockade designed to limit Iranian oil exports, shipments are continuing through increasingly elusive maritime strategies. Recent information from maritime intelligence firm Windward indicated that the number of vessels operating without tracking signals has surged, complicating enforcement efforts.

In one report, it was revealed that 146 out of 167 vessels in the region were not broadcasting their location data.

Additionally, analysts from Windward have noted ongoing covert loading operations on Kharg Island, Iran’s primary export site, with large oil tankers remaining untracked despite escalating enforcement activities.

“I wonder if this development significantly alters things, considering how China has helped Iran evade sanctions,” Meizlisch expressed.

This oil flow has been largely driven by demand from Chinese refiners, particularly smaller, independent operators who often function outside the U.S. financial system, thus facing less sanction-related pressure.

“This seems to be a clear attempt by the Chinese government to shift the responsibility back onto the U.S. and see how that plays out,” added Maizlisch.

The decision by the Chinese government to formally instruct its companies to ignore U.S. sanctions introduces new risks for global companies. The blocking law enables Chinese entities to pursue damages in local courts against banks or shipping firms that opt to sever ties to comply with U.S. regulations.

Analysts foresee that this move could put multinational companies in a precarious position, requiring them to balance access to Chinese markets with the risk of being excluded from the U.S. financial system.

“China is the most crucial supporter of Iran,” Meizlish stated.

This standoff underscores broader challenges for the United States. While sanctions are a key element of U.S. foreign policy, they pose a greater challenge when targeting major economies like China, especially when transactions occur outside the dollar-based system.
