This would be the first meeting between the two leaders, who along with premiers of six other SAARC member countries - Bhutan, Bangladesh, Sri Lanka, Maldives, Nepal and Afghanistan - are attending the Colombo summit. Afghan President Hamid Karzai would be attending the summit for the first time as his country was made a member of the Saarc last year.
Gilani had called Manmohan Singh on Thursday to congratulate him on winning the trust vote in the Parliament.
According to reports in the Pakistani media, Gilani told Singh during their telephonic conversation that Pakistan attaches immense importance to its relations with India and the "two countries should jointly work toward combating terrorism."
Gilani's call assumes importance in view of recent blast in the Indian mission in Kabul, which is being attributed both by the Indian and the Afghanistan to Pakistan. However, Gilani told Manmohan Singh that "The present state of unrest in the region demands more cooperation for combating terrorism and extremism as both countries are victims of this menace," reports said.
Gilani also told Singh said that he was hopeful of both the countries would be able to resolve all their "outstanding issues amicably."
