South Sudan President Salva Kiir on Saturday flew to Ugandan and met President Yoweri Museveni.
According to a short State House statement, Museveni on Saturday afternoon held secret talks with Kiir at State House, Entebbe.
They focused on regional issues but mostly importantly how to ensure that peace and stability returns to South Sudan.
At the close of the week, Kiir appealed to his rival Riek Machar to return to the capital and help rebuild the peace after a wave of deadly gun battles threatened to plunge the country back into civil war.
The whereabouts of Machar, the rebel leader who was reappointed vice president as part of a peace deal to end almost two years of bitter conflict, are not known.
“I am appealing to Dr Riek Machar to return back to Juba so that we can continue with the implementation of the peace agreement (which) … needs the two of us to implement,” Kiir said in a statement.
He said he pledged his “100 percent commitment” to ensuring Machar’s security while in Juba, following the intense fighting that erupted between rival troops just as the two men were meeting in the capital on July 8.
Machar rejected the ultimatum saying he would only return if regional force is deployed to protect him.
Museveni had suggested the deployment of a regional force to Juba while meeting UN Secretary General Ban Ki moon in Kigali during the African Union summit.
Machar has not been seen since he left Juba after days of fierce fighting that claimed the lives of at least 300 people and sent tens of thousands fleeing, many to Uganda.
The unrest in the world’s youngest nation left an August 2015 peace deal hanging by a thread.
Tens of thousands of people have been killed since the war first erupted in December 2015 when Kiir accused Machar, then his vice president, of plotting a coup.
More than two million people have also been driven from their homes in the conflict, which has reignited ethnic divisions and been characterised by gross human rights abuses.
