Modi, who arrived here on Tuesday to attend 18th SAARC Summit, held talks with the SAARC leaders at the Soaltee hotel where all the visiting dignitaries are staying.
During his meeting with Afghanistan President Ashraf Ghani, Modi said India was committed to strengthening relations with the war-torn country.
Prime Minister Modi and his Bangladeshi counterpart Sheikh Hasina discussed greater prospects of cooperation amongst democracies of South Asia, according to the External Affairs Ministry Spokesperson.
Inviting Bhutan Prime Minister Tshering Tobgay to visit 'vibrant Gujarat' event in January, the Indian leader also appreciated Bhutan National Reading Year - 2015, and committed to send experts who organised 'Gujarat is Reading'.
Tobgay also welcomed Modi's leadership role in SAARC.

Later, the Afghan sources said President Ghani and Prime Minister Modi discussed key issues, including defence cooperation.
Their discussion comes in the backdrop of Afghanistan wanting to get military supplies, including weapons, in the face of the withdrawal of NATO troops from there.
The sources said the two leaders also discussed the security situation in Afghanistan, where recently a terror strike at a volleyball match claimed 57 lives.

Modi also held a bilateral meeting with Sri Lankan President Mahinda Rajapaksa during which he thanked him for pardoning and sending back five Indian fishermen, who were sentenced to death for alleged drug trafficking.

During the meeting, which lasted for nearly 30 minutes, the two leaders discussed important bilateral and regional issues. This is the third meeting between the two leaders since Modi took over as Prime Minister in May.
Rajapaksa attended Modi's swearing-in after which they held a bilateral meeting. Later, the two met on the sidelines of the UN General Assembly in New York in September.
Asked if Modi thanked him for the release of fishermen, Rajapaksa said that,"I said we must thank Modi for his foreign policy, it (release of fishermen) happened due to that."
"The relationship between India and Sri Lanka is very good," he said.
Five Indian fishermen sentenced to death in Sri Lanka for alleged drug trafficking were released last week after President Rajapaksa pardoned them.
The fishermen were apprehended in November 2011 and sentenced to death by the Colombo High Court on October 30 for alleged drug trafficking.
Rajapaksa commuted the death sentence after Prime Minister Modi had a telephonic conversation with him on the issue.
The Sri Lankan leader also welcomed Modi's initiative to develop and launch a satellite dedicated to SAARC.
During his address at the 18th SAARC Summit, Modi wished "good luck" to Rajapaksa for the January polls in Sri Lanka.
Later, Modi also met Maldivian President Abdulla Yameen during which the two leaders discussed economic ties and maritime cooperation.
