President Pranab Mukherjee and Prime Minister Narendra Modi formally welcomed Sri Lanka's President Maithripala Sirisena to India in the forecourt of the Rashtrapati Bhavan here on Monday.
President Sirisena was also given a ceremonial tri-services guard of honour.
The national anthems of both nations were also played on the occasion.
Earlier, President Sirisena paid homage at the Rajghat memorial of Mahatma Gandhi.
President Sirisena will hold delegation-level talks with Prime Minister Narendra Modi at Hyderabad House this afternoon. He will also have a meeting with External Affairs Minister Sushma Swaraj.
The meeting with Prime Minister Modi will be structured both in terms of a restricted format as well as delegation level talks.
Both the leaders are expected to take steps to scale up economic cooperation between the two countries.
After the talks, some agreements are likely to be signed in the field of culture, people-to-people contact and agriculture.
President Pranab Mukherjee will also host a banquet in the honour of the Sri Lankan dignitary.
On Tuesday, the Lankan President will travel to Bodh Gaya and later to Tirupati. The President is expected to depart from Tirupati for Colombo early on Wednesday.
This is President Sirisena's first overseas visit after assuming office.
