A scheduled trip by a U.S. trade delegation to India later this month has been called off, according to reports. Several rounds of talks on a bilateral trade deal between the U.S. — the world's largest economy — and India, the world's most populous nation and itself a major economic power, have so far failed to yield an agreement.

(Reuters) -A planned visit by U.S. trade negotiators to New Delhi from August 25-29 has been called off, a source said, delaying talks on a proposed trade agreement and dashing hopes of relief from additional U.S. tariffs on Indian goods from August 27.
