South Sudan's peace monitors on Monday called on warring parties to develop effective and inclusive ways to engage local population in the implementation of a revitalized peace agreement.

Augostino Njoroge, deputy chairperson of the Joint Monitoring and Evaluation Commission (JMEC), urged the National Pre-Transitional Committee to champion the responsibility of uniting the war-affected communities to promote healing and reconciliation in the country.

"It is evident that the huge responsibility bestowed upon you requires the collaboration of regional and international actors. This behooves you to develop an effective and transparent mechanism to bring on board those important partners," Njoroge said in a statement issued in Juba.

On Sunday, the JMEC inaugurated the first meeting of the National Pre-Transitional Committee in the Sudanese capital, Khartoum, to discuss the formation of the next transitional government.

The 10-member committee is required to submit monthly written reports to the chairperson of the Reconstituted JMEC, the parties and other stakeholders.

"Experience has shown that a failure to secure the requisite financing for such crucial institutions can severely undermine and ultimately stall implementation," said Njoroge.

President Salva Kiir and Riek Machar, leader of the Sudan People's Liberation Movement-in-Opposition (SPLA-IO), agreed to the final peace deal mediated by Sudanese President Omar al-Bashir under the auspices of the Intergovernmental Authority on Development (IGAD), an east African bloc.

South Sudan's conflict erupted in 2013 after forces loyal to Kiir and his former deputy Machar engaged in combat.

A 2015 peace agreement was violated in July 2016 when rival factions resumed fighting in the capital Juba, forcing Machar to flee into exile.

Millions of South Sudanese civilians have sought refuge in neighboring countries.
