Iran Vows Devastating Response to US Toughest-Ever Sanctions
The United States says it plans to put very strong economic pressure on Iran.
U.S. officials say the sanctions and a naval blockade are meant to force Iran to change and could bring down its leadership.
Iran says it will respond forcefully if the United States makes new threats.
Iranian officials also say the sanctions are unfair and are meant to weaken Iran’s independence.
The pressure has affected oil shipments through the Gulf region and the Strait of Hormuz.
Fewer Iranian oil offers are now reaching Chinese buyers.
China buys more than 80% of Iran’s shipped oil, according to data cited in the reports.
China says sanctions will not solve the disagreement and wants diplomacy instead.
Earlier ceasefire agreements between the United States and Iran quickly collapsed.
Iranian military chief Ali Abdollahi threatened a broad, decisive response to any new U.S. threats.
U.S. Treasury Secretary Scott Bessent said Washington would impose its toughest-ever sanctions and seek to collapse Iran’s leadership.
Iranian officials condemned the measures as economic terrorism and accused the United States and Israel of economic and cognitive warfare.
A U.S. naval blockade reimposed on Iranian ports in July has reduced crude offers to Chinese buyers.
China opposed sanctions and urged the parties to resolve the conflict through political and diplomatic means.
