"This visit has been extremely successful and entirely satisfying. It will further strengthen Indo-Bhutan ties," External Affairs Minister Sushma Swaraj told mediapersons.
Swaraj said, during the two-day trip, the prime minister interacted with all the three wings of the democracy in Bhutan - the executive, the judiciary and the legislature.
The prime minister called on Bhutan King Jigme Khesar Namgyel Wangchuck and held talks with the landlocked country's prime minister Tshering Tobgay. He also inaugurated a new building of the country's Supreme Court at Hejo which has been built with Indian funding and Monday addressed a joint session of Bhutanese parliament.
Swaraj said India was "deeply, deeply" moved by the hospitality extended to and the love and affection showered on Modi with the king "personally supervising all arrangements".
"The prime minister (Modi) gave some new suggestions to the Bhutanese leadership like holding a sports festival where India's northeastern states and Nepal and Bhutan both participate," Swaraj said.
The prime minister also reaffirmed all commitments made by the previous UPA government to Bhutan on various issues.
He said: "We will fulfil all the commitments in toto as the commitments were not given merely by a government but were made by one country to another."
