China Rejects New US Sanctions Targeting Iran and Its Trading Partners

China has strongly criticised a fresh round of US sanctions aimed at Iran, warning Washington that Beijing will take steps to protect its economic interests.

The dispute follows the announcement of wider measures by the United States designed to put further pressure on Iran's economy and restrict the financial networks used by Tehran to sell oil and generate revenue.

US Treasury Secretary Scott Bessent described the campaign as an unprecedented financial offensive against Iran. He warned that banks, companies and countries continuing to do business with Tehran could also face consequences.

For China, however, the message from Beijing was clear: it does not accept the US imposing sanctions on Chinese businesses simply because they trade with Iran.

Beijing promises to defend its interests

Chinese Foreign Ministry spokesman Lin Jian said Beijing was firmly opposed to what China considers unilateral and unlawful American sanctions.

He argued that Chinese-Iranian trade is carried out within international law and should not be disrupted by Washington.

China is particularly important to Iran because it remains the country's biggest buyer of oil. Much of Iran's crude exports are ultimately destined for Chinese markets, making Beijing a crucial part of Tehran's ability to withstand American economic pressure.

The latest confrontation could therefore prove difficult for Washington if China refuses to comply with the new measures.

Bessent has warned that nobody should consider themselves beyond the reach of US sanctions, including Chinese financial institutions.

Washington turns up the pressure

The US has named its latest campaign “Operation Economic Outcast”, as President Donald Trump's administration attempts to further restrict Iran's access to international finance.

American officials say the new measures target companies, individuals, vessels and financial networks accused of helping Iran bypass existing sanctions.

Washington's objective is to reduce Iranian revenue and increase pressure on Tehran following months of conflict and failed diplomatic efforts.

However, there are already questions about how effective the measures will be.

With a large proportion of Iranian oil exports going to China, analysts believe Beijing's willingness to continue purchasing Iranian energy could significantly limit the impact of the sanctions.

China and the US face another confrontation

The timing is particularly sensitive, with Trump and Chinese President Xi Jinping expected to hold talks next month.

Washington will also have to consider the possibility of retaliation from Beijing. China plays a major role in global supply chains for rare earth elements and other critical minerals used in advanced technology and manufacturing.

Beijing has previously used export controls on rare earths as leverage during trade disputes with the United States.

That means a dispute over Iran could potentially develop into another wider confrontation between the world's two largest economies.

Iran says it is prepared

Tehran has also dismissed the latest American measures, insisting that it has been preparing for increased economic pressure.

Iranian Economy Minister Ali Madanizadeh said the government had plans in place to deal with the sanctions and suggested Washington's strategy would ultimately fail.

Iran has already spent years operating under US sanctions and has developed networks designed to keep trade and oil exports moving despite restrictions.

Analysts remain divided over whether the latest measures will significantly reduce Iranian oil revenues.

For now, the immediate result appears to be another major clash between Washington and Beijing — with Iran's oil trade at the centre of the dispute and businesses around the world potentially caught between the competing economic powers.
