Russia will help India build at least 10 more nuclear reactors, Indian Prime Minister Narendra Modi has said following a visit by Russian President Vladimir Putin.
The two countries signed a series of major energy agreements on Thursday.
Russia will also remain India’s top defence supplier, said Mr Modi.
Mr Putin’s visit to Delhi comes as India faces energy shortages and Russia seeks to expand its ties with Asia in the face of Western sanctions.
Mr Modi said that the two countries had outlined an “ambitious vision” for nuclear energy during the talks and that the new reactors would be built over the next 20 years.
He added that, under the deal, nuclear components would be made in India.
