ISLAMABAD: US national security adviser Susan E. Rice is scheduled to arrive in Pakistan on Sunday on a day long official visit, it has been learnt.

According to details, Rice is expected to meet Pakistan's political and military leadership during which discussions will be held on bilateral relations and the regional security situation.

Rice will be accompanied by a high-level delegation and will hold important talks with Prime Minister Nawaz Sharif tomorrow.

Moreover, a top military source said that the US national security adviser will hold a separate meeting with Chief of Army Staff General Raheel Sharif at the General Headquarters, where the regional security situation will come under discussion.

Rice's visit comes on the heels of cancellation of talks between India and Pakistan's national security advisers. Expressing disappointment at the cancellation of the proposed talks between the NSAs of the two countries, the United States had urged the neighbours to soon resume formal dialogue.

“We are disappointed that the talks will not happen this weekend and encourage In­­dia and Pakistan to resume formal dialogue soon,” State Department spokesman John Kirby had said.

The region also recently saw suspension of the Afghan peace talks after news of Mullah Omar's death surfaced and it is likely that the subject may come under discussion during tomorrow's talks.
