China says it will protect its interests as US expands Iran sanctions

Washington has warned that any country that continues to engage in commercial transactions with Tehran could face diplomatic and economic isolation. The United States’ statement follows a series of sanctions aimed at curbing Iran’s ability to fund its nuclear and regional activities, and it specifically targets nations that purchase or facilitate the transport of Iranian oil.

Iran’s oil exports have increasingly been channeled to China, which now accounts for the majority of Tehran’s petroleum sales after European buyers reduced purchases under Western pressure. U.S. officials say the threat seeks to compel third‑party states to abandon the lucrative but sanctioned trade, warning that continued cooperation could result in restrictions on financial services, trade privileges and access to American markets. The move underscores ongoing tensions over Iran’s energy ties and the broader effort by Washington to enforce its sanctions regime.
