India and the US are continuing to actively engage on trade deal negotiations, Sergio Gor, the new US ambassador to India, has said during a trip to Delhi.

The next call to discuss the deal was scheduled for Tuesday, Gor said, but did not elaborate on who would participate.

He also said the friendship between US President Donald Trump and Indian PM Narendra Modi was real and that "real friends can disagree but will always resolve their differences at the end".

Gor's remarks come just days after some US officials blamed India for the delay in signing the deal, a claim that Delhi has denied.

Trade negotiations between the nations have been strained since the US imposed 50% tariffs on Indian goods - the highest in Asia - in August, including penalties linked to India's purchase of Russian oil. Washington has pushed for greater access to India's agricultural sector, a long-standing sticking point which Delhi has strongly resisted.
