Pakistan Prime Minister Nawaz Sharif inaugurated the 'Heart of Asia' summit in Islamabad in the presence of Indian foreign minister Sushma Swaraj and Afghanistan's President Ashraf Ghani on Wednesday. 

Sharif addressed the issue of terrorism and called for collective efforts of the Asian nations in fighting the menace posed by terror groups such as Isis. 

"The emergence of newer and more threatening terrorist groups like Daesh should strengthen our resolve against terrorism," Sharif said at the conference. 

"We should envisage collective and coordinated measures on regional security front to ensure gains in struggle against terrorism are durable," he said. 

Swaraj, who is the first minister from the Modi government to visit Pakistan, attended a dinner hosted by Prime Minister's adviser on foreign affairs Sartaj Aziz on Tuesday. 

She will meet Sharif on Wednesday on the sidelines of the summit, while foreign policy officials of the two neighbouring countries will hold much-delayed talks. 

The thaw in Indo-Pak relations came after Indian Prime Minister Narendra Modi's meeting with the Pakistani PM in Paris earlier this month, which led to a secret meeting between the national security advisers of the respective countries in Bangkok on Sunday.
