Trump 'optimistic' about trade deal with India

New Delhi and Washington are yet to sign a trade deal, but the two countries would begin talks to strike a comprehensive agreement, Trump and Indian Prime Minister Modi said.

The two countries have been trying to close differences over farm goods, medical devices, digital trade and proposed new tariffs.

Modi is pulling all the stops for Trump's visit seen as a deepening of ties between the world's biggest democracies that are trying to counter the economic and military weight of China in Asia.
