It's the first dinner Trump and first lady Melania Trump have hosted for a foreign dignitary at the White House.
Senior administration officials who prepared Trump for Monday's meeting said Trump is aware of the delicate balance with India and Pakistan, but will look to treat the 1.3 billion person country like the defense ally it is, including by selling the kind of "technology that the United States provides to its closest allies and partner".
President Donald Trump is thanking India for purchasing US military equipment.
India's leader is in the USA for his first meeting with President Donald Trump, seeking to build on growing ties between the world's two largest democracies and move beyond disagreements over climate change. The US President said that he had read a lot about Modi and congratulated him for the "exemplary leadership he has shown, primarily, economically".
Immigration is expected to be a major topic of discussion and possible source of tension between the two world leaders.
Trump was speaking at the formal dinner with Modi at the historic Blue Room of the White House. "I think it was nothing other than convenience", he said.
President Donald Trump on Thursday will lay out his plan for reducing regulations to boost already-abundant US production of oil, natural gas and coal and export it around the world, creating American jobs and helping allies.
Modi laid special emphasis on ties between India and the United States and praised the USA as a valued partner. he also asserted that eliminating safe havens of terror and bringing stability to Afghanistan was the major issue that both nations need to address.
"Secretary Mattis began by referring PM Modi's Opinion piece in the Wall Street Journal in which he writes about expanding partnership and taking it on an upward trajectory".
During the meeting with Tillerson which covered strategic areas and economic cooperation, Modi defined the Indo-US ties as the "defining partnership" and said it has a global importance.
Jaishankar also said there were discussions on issues in the Indian Ocean region, Middle-East in the context of security, and on Afghanistan, particularly the United States policy review on it.

While issues like defense spending will define Monday's visit, the goal of Trump and Modi's afternoon together is also aimed at getting their relationship off on the right foot. I have heard so much and I have been reading so much about you.
The two leaders, who held a meeting at the White House on Monday, also "called on all nations to resolve territorial and maritime disputes peacefully and in accordance with worldwide law", the statement said.
So far, Modi and Trump have had two phone calls together and administration officials are hopeful they can find common ground.
While there were no major announcements, Trump's administration confirmed it had given the green light to the $366 million sale of a transport carrier to India, along with a separate purchase of around 20 drones.
"I look forward to working with you, Mr prime minister, to create jobs in our countries, to grow our economies and to create a trading relationship that is fair and reciprocal".
Trump, who described Modi as a "true friend!" on Twitter after his weekend arrival in the United States, should find much in common with the Indian leader, with both men having won power by portraying themselves as establishment outsiders.
Modi in turn made Trump smile by hailing the property tycoon's reputation as dealmaker.
India is now the world's fastest growing major economy, a status that Modi is hoping to cement by drawing in more foreign investment ─ in part by encouraging manufacturers to do business in Asia's third-largest economy.
Administration officials expected India to raise concerns about restrictions on certain exports.
The same could be said for the thousands of Indians studying in the United States, whose talents can benefit both countries.
At the same time, one reason Beijing is not overly concerned is that in its view, ahead of India on the agenda for Trump is dealing with North Korea.
