The United States has cancelled a delegation visit to New Delhi that was scheduled for 25–29 August, delaying the sixth round of negotiations on a proposed bilateral trade agreement, according to multiple media reports citing people familiar with the discussions. The Office of the U.S. Trade Representative and India’s Ministry of Commerce have not commented, and no new date has been set for the talks. The postponement comes less than two weeks before an additional 25 percent U.S. tariff on Indian goods is due to take effect on 27 August. The surcharge will lift the cumulative U.S. duty on some Indian exports to as high as 50 percent, the highest rate applied to any trading partner. Washington has linked the latest levy to New Delhi’s continued purchases of Russian oil. Five earlier negotiating rounds failed to bridge gaps over U.S. demands for wider access to India’s farm and dairy markets and American objections to India’s energy ties with Moscow. Indian officials have argued that the country is being unfairly singled out, noting that Western nations continue trading with Russia. The United States is India’s largest single export destination, accounting for roughly 20 percent of shipments—or $86.5 billion—in the fiscal year to March 2025. Trade analysts warn that the collapse of the August session reduces the likelihood of short-term tariff relief and adds fresh uncertainty to wider economic and strategic ties between the two democracies.
