- Colourful pageantry greeted Trump as he travelled in armoured car
- Donald Trump's visit comes amid tense trade talks between India, US
- "Namaste, Trump" being seen as parallel to "Howdy, Modi!"
Here are the top 10 points as Donald Trump visits India:
"It is our pleasure to welcome and greet President Donald Trump, First Lady Melania Trump, Ivanka Trump and Jared Kushner... Their visit to India shows the importance the closeness in ties we share," PM Modi said.
"The rise of India in the last seven decades has been remarkable... The pace at which it has grown in the last two decades is phenomenal... The people of India are an inspiration for the rest of the world," President Trump said.
"Every nation has the right to secure and control borders. The US and India have been working to stop terror and fight their ideology. My administration has been working successfully with Pakistan in fighting terror... India has a leadership role in promoting peace in the region," he said.
The two-day state visit comes ahead of President Trump's re-election bid - the US votes in November - and just months after PM Modi's "Howdy, Modi!" event in Texas last year. Mr Trump's visit also comes amid tense trade talks between the two countries.
President Trump's convoy passed through the Sardarnagar area of Ahmedabad, which contains several slums. A four-foot tall, 500-metre-long wall has been built along this section, which residents say is meant to "hide the poor people" ahead of Mr Trump's visit. Local officials, however, say the decision to build the wall was taken well before the presidential visit.
At Mahatma Gandhi's Sabarmati Ashram, President Trump and the First Lady tried their hand at spinning the charkha as PM Modi explained the significance of the traditional spinning wheel to the visitors. PM Modi was seen showing the Trumps around the revered ashram and explaining the marble depiction of Gandhi's three monkeys to Melania Trump.
President Trump and his family were served high tea, which, reports said, featured broccoli samosas and apple pie. "Namaste, Trump" is being seen by many as a parallel to the lavish "Howdy, Modi!" event organised for PM Modi in Houston.
From Ahmedabad, Donald Trump and his family travelled to Agra where they visited the Taj Mahal and were given a private guided tour. "The Taj Mahal inspires awe. A timeless testament to the rich and diverse beauty of Indian culture! Thank you India," President Trump wrote in the visitor's book. Chief Minister Yogi Adityanath, hundreds of artistes welcomed the Trumps at the airport with beautiful performances reflecting the rich culture of Uttar Pradesh. President Trump and his family flew to Delhi on Monday evening for the operative part of the trip, which includes high level talks tomorrow.
An Indo-US trade deal is likely to be discussed. Apart from growing protectionism, Donald Trump's visit also comes against the backdrop of India's multibillion-dollar purchase of a Russian missile shield system.
First Lady Melania Trump's scheduled visit to a Delhi government school has also drawn controversy after Delhi Chief Minister Arvind Kejriwal and Deputy Chief Minister Manish Sisodia were dropped from the event. Tensions between Mr Kejriwal's AAP, which rules Delhi and PM Modi's BJP, in power at the centre, spiked after a bitterly fought Delhi Assembly election last month that the AAP won. Late Sunday evening the US embassy issued a clarification.
