NEW DELHI: India has postponed plans to send a trade delegation to Washington this week a source in the country’s Ministry of Commerce and Industry said, following uncertainty after the United States Supreme Court struck down tariffs imposed by former President Donald Trump.

The delegation was scheduled to depart Sunday to finalize an interim trade agreement under which the U.S. would reduce punitive 25% tariffs on certain Indian exports tied to Russian oil purchases, while India would buy U.S. goods worth $500 billion over five years. Proposed tariff cuts would lower U.S. duties on Indian exports to 18%.

The decision to defer the visit was taken after discussions between officials of the two countries the source said requesting anonymity. No new date has been set.

India’s opposition Congress party criticized the interim pact urging renegotiation and questioning Prime Minister Narendra Modi’s joint statement prior to the court ruling.

Trade Minister Piyush Goyal had previously indicated the interim deal could take effect in April, following resolution of outstanding issues during the delegation’s visit. India is now reviewing the court judgment and subsequent U.S. announcements before proceeding.
