Washington, Jan 14 (Agencies): As a UN mission overseeing Nepal's transition to peace prepares to wind up, the US has appealed to the political leadership in the country to respect their own commitment and bring the peace process to "a much-needed conclusion".

Assistant Secretary of State for South and Central Asia, Robert Blake, made separate telephone calls to the Nepalese Prime Minister Madhav Kumar Nepal and the chairman of the Communist Party of Nepal Pushpa Kamal Dahal, popularly known as Prachand.

"He (Blake) told both leaders that the US Government commitment to support the peace process will continue after the United Nations mission leaves Nepal this weekend," State Department spokesman PJ Crowley said.

"He urged all parties to continue to respect their own commitments under the comprehensive peace agreement," Crowley said.

The UN mission in Nepal was set up in 2007 with a one-year mandate to oversee the country's transition to peace.

It was repeatedly extended, but in September the United Nations announced the mission would close on January 15.
