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".

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".

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.

So far, Modi and Trump have had two phone calls together and administration officials are hopeful they can find common ground.

"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.
