US Special Envoy Scott Gration will leave for Sudan on Monday, in an effort to push related parties to fully and completely implement the comprehensive peace agreement, said US State Department.

The envoy will travel to Juba, southern Sudan, to finalize agreement on a bilateral action plan between the Sudan People's Liberation Movement (SPLM) and the National Congress Party (NCP) to ensure "the full and complete implementation of the Comprehensive Peace Agreement (CPA) in advance of critical election and referenda milestones in 2010 and 2011, respectively," said a statement.

The bilateral action plan advances critical elements of the CPA, added the statement.

During the visit, which will be from Aug. 17 to 24, Gration will continue bilateral discussions with the SPLM in Juba and the NCP in Khartoum. He will also visit Ethiopia to resume talks with the leadership of key Darfuri armed movements on unification efforts in support of the Doha peace process.

From Addis Ababa, the envoy will travel to Cairo, Egypt, for meetings with senior officials from Egypt, Sudan, Libya and Arab League Secretary General Amr Moussa, said the statement.
