Iran has pledged to retaliate against any nation cooperating with fresh US sanctions, as Washington launches a campaign to economically isolate Tehran that hinges on the response of major trading partners such as China, India and Russia.
Tehran has vowed to retaliate against any country that cooperates with the United States’ attempt to impose fresh sanctions on Iran, according to the Guardian. The US Treasury secretary, Scott Bessent, described the measures as “the single greatest financial offensive ever marshalled against an adversary.”
The US has threatened to impose severe sanctions against any country or entity maintaining economic ties with Iran, the Guardian reported. Washington is hoping to achieve through economic measures what military means have so far failed to accomplish, launching a campaign to isolate Tehran.
Ahead of the US announcement, the United Arab Emirates, described as Iran’s single biggest trading partner in the Middle East, announced it was ending all trade with Iran. Tehran believes the move was coordinated between Washington and the UAE.
A key test of the US rhetoric will rest on whether major economies such as India, China and Russia view the economic threats as credible. The effectiveness of the sanctions campaign is likely to depend on the willingness of these countries to comply.
However, it remains unclear how far the Trump administration is prepared to go in confronting China, which is Iran’s biggest trading partner. Beijing has signalled its resistance to US economic pressure to cut off links with an ally.
The uncertainty over whether Washington would apply sanctions directly to China underscores the difficulty of the campaign, as the credibility of the threats may ultimately hinge on how the US handles its largest economic rival.
Why it matters
The confrontation pits the US financial system against Iran's most important trading partners, with the outcome likely to test whether economic pressure can succeed where military action has not. How China, India and Russia respond could reshape global trade flows and signal the limits of US sanctions power.
