The meeting will take place at 12.15 p.m. local time (9.45 p.m. IST), Ministry of External Affairs spokesman Raveesh Kumar said at a briefing here on Monday.
When asked about Trump saying that he'd heard a "very aggressive" statement by Modi at the 'Howdy Modi' event, Kumar declined to reply, saying: "There is a meeting tomorrow (Tuesday)between the Prime Minister and the US President, let us wait for it."
Trump, who renewed his offer to mediate on Kashmir during a media interaction here alongside Pakistan Prime Minister Imran Khan, said on Monday that he had heard a "very aggressive" statement by Modi during Sunday's event.
To a question if he was concerned about the human rights situation in Kashmir, Trump said: "Sure. I'd like to see everything work out. I want it to be humane. I want everybody to be treated well. You have two big countries, and they're warring countries and they've been fighting.
"And I mean, I heard a very aggressive statement yesterday. I don't have to say that. I was there. I didn't know I was going to hear that statement. But I was sitting there and I heard a very aggressive statement yesterday from India, from the Prime Minister, and I will say it was very well received within the rule, you know, within in the room.AThe statement itself. That was a big room; there were 59,000 people.
"But it was a very aggressive statement, and I hope that they're going to be able to come together, India and Pakistan, and do something that's really smart and good for both..."
