The US is threatening to cut off financial access for anyone trading with Iran. China, Iran’s biggest oil buyer, says it won’t comply.

China condemned the latest U.S. sanctions on Iran, vowing to protect Chinese companies as the world's top buyer of Iranian crude. The dispute adds friction ahead of next month's high-level talks between American and Chinese leaders, where supply chains and critical minerals are expected to dominate the agenda

Beijing has forcefully criticized the latest expansion of U.S. economic sanctions against Iran, vowing to take all necessary measures to defend Chinese enterprises and trade interests. The response follows Washington’s announcement of a broad financial initiative targeting Iran and any international partners maintaining commercial relations with Tehran, according to BBC News.

Chinese Foreign Ministry spokesperson Lin Jian stated that Beijing opposes unilateral sanctions imposed outside international legal frameworks, emphasizing that legitimate trade and economic cooperation between China and Iran should not face external interference. China remains the world’s primary buyer of Iranian crude oil, and Chinese authorities have consistently rejected non-multilateral trade restrictions.

The friction comes as Washington unveils an aggressive campaign aimed at isolating Iran’s financial and energy networks. U.S. Treasury Secretary Scott Bessent announced measures targeting dozens of entities, vessels, and facilitators accused of circumventing existing embargoes to move Iranian petroleum. American officials warned that global institutions continuing financial dealings with Tehran risk losing access to the U.S. financial system.

In Tehran, Iranian officials dismissed the new economic measures, declaring that the country has implemented a strategic plan to insulate its economy and manage external pressures. Iranian leaders noted that previous economic restrictions failed to force policy changes, asserting that internal financial mechanisms remain in place to mitigate potential disruptions.

Economic and geopolitical analysts have questioned the immediate effectiveness of the newly announced measures, pointing out that previous unilateral actions struggled to curb energy flows to nations that do not recognize U.S. sanctions. Observers also note that several of Iran’s regional neighbors maintain essential trade ties with Tehran that cannot be easily severed without causing local economic disruption.

The escalating diplomatic dispute adds friction to the broader international climate ahead of scheduled high-level bilateral talks between top American and Chinese leaders next month, with global supply chain dependencies and critical mineral trade expected to feature prominently on the economic agenda.
