China has strongly denounced the United States' decision to expand economic sanctions against Iran and its trading partners, including Beijing, declaring the measures "illegal" and pledging to take necessary actions to safeguard its national interests.

The condemnation from China's Foreign Ministry spokesman, Lin Jian, came shortly after U.S. Treasury Secretary Scott Bessent announced the new sanctions on Monday. Bessent warned that any nation financially engaging with Iran would face isolation, signaling a significant escalation in U.S. pressure on Tehran.

Lin stated that cooperation between China and Iran consistently adheres to international law and should not be subjected to external interference. He emphasized that China would not allow its legitimate trade and economic activities to be disrupted. U.S. Treasury Secretary Bessent, while not naming specific countries, indicated that banks and businesses refusing to cut ties with Iran would be treated as complicit in Tehran's isolation.

The expanded sanctions, dubbed "Operation Economic Outcast" by the U.S. Treasury, are seen as a substantial financial offensive against Iran, particularly in the context of the ongoing Iran war and its impact on global oil prices and trade routes like the Strait of Hormuz.

This U.S. move occurs ahead of anticipated talks between U.S. President Donald Trump and Chinese President Xi Jinping next month. Beijing's strong reaction suggests potential friction during these discussions, as Washington is aware of China's critical role in processing rare earths and other vital minerals essential for high-tech manufacturing.

Iran's Economy Minister, Ali Madanizadeh, expressed confidence in Tehran's preparedness for the widened sanctions. He asserted that Iran has a two-year plan to manage the economic impact and possesses its own strategies to counter the U.S. measures, suggesting the sanctions would ultimately prove unsuccessful.

The U.S. sanctions follow failed diplomatic efforts to resolve the Iran war, which has already disrupted global energy markets and led to a naval blockade by the U.S. and effective export blockades by Iran through the Strait of Hormuz. The recent expiration of a 60-day ceasefire highlights the lack of a clear path toward peace.

Treasury Secretary Bessent made it clear that no entity, including Chinese banks, would be exempt from the reach of U.S. sanctions, underscoring Washington's determination to enforce its economic policies and potentially isolate Iran's financial lifelines.
