India and the US have signed defence, energy and telecoms deals but failed to reach a much-talked about trade accord.
President Donald Trump hailed a “very productive visit” but said he would keep working with Indian PM Narendra Modi for “a comprehensive trade deal”.
The US is one of India’s biggest trade partners. The two leaders hope the visit will mend a rift over tariffs.
Mr Trump’s visit to Delhi has been marred by the deadliest religious unrest in the capital for decades.
Seven people, including a policeman, have been killed and about 150 injured in protests against a controversial new citizenship law, which critics say discriminates against Muslims.
Mr Modi’s Hindu nationalist government denies this, saying the law only seeks to give amnesty to persecuted minorities.
Correspondents say the timing of the unrest is an embarrassment to Mr Modi as he hosts the US president and the violence has taken the spotlight away from Mr Trump’s visit.
Mr Trump began the second day of his trip at the presidential palace, Rashtrapati Bhavan, where he was given a ceremonial welcome. He later held talks with Mr Modi.
Both leaders acknowledged they had not been able to sign a trade deal, but announced that negotiations would continue.
“Our commerce ministers have had positive talks on trade. Both of us have decided that our teams should give legal shape to these trade talks. We also agreed to open negotiations on a big trade deal. At the global level, our relationship is depended on the similar democratic values we share,” Mr Modi said.
But deals in other areas were announced.
India is to buy attack helicopters and other US military equipment worth $3bn, Mr Trump said as the two men delivered a joint statement.
“We also discussed defence in detail and have agreed on a comprehensive defence deal. The deal would include procurement of 24 MH-60 Romeo helicopters by India. Another contract to acquire six AH-64E Apache helicopters,” he said.
They also announced co-operation in fighting radical Islamist terrorism and deepening energy ties, as well as pledging to work together to make 5G technology safer. As part of the deals announced, US firm Exxon Mobil and Indian Oil have signed an agreement to help India import more Liquefied Natural Gas (LPG).
Bilateral trade between the two countries totalled $142.6bn (£110.3bn) in 2018. But in June 2019, the US ended preferential trade status for India, the largest beneficiary of the Generalized System of Preferences (GSP) – a scheme that allows some goods to enter the US duty-free.
India imposed retaliatory tariffs on 28 US products, causing a diplomatic rift between the two countries.
But Mr Trump’s visit has helped improve relations, and cement what appears to be a strong personal rapport between him and Mr Modi.
Mr Trump’s two-day India visit has been high on optics. Tens of thousands of people lined the streets of Ahmedabad city in Gujarat, the home state of Mr Modi, to welcome him on Monday. The leaders later addressed a crowd of more than 100,000 people at the Motera cricket stadium. Mr Trump ended the day with a city to the iconic Taj Mahal.
“The last two days, especially yesterday at the stadium, it was a great honour for me. People were there maybe more for you [PM Narendra Modi] than for me… Every time I mentioned you, they cheered more. People love you here,” President Trump said.
