The delegation, which includes officers from China's Central Military Commission, the Chinese Foreign Ministry as well as medical experts were received by Chinese Ambassador to Uganda, Zhao Yali at Entebbe International Airport, about 40 kilometers, south of the capital, Kampala.

Three of the injured Chinese and Rwandan peacekeepers who were also wounded in the Sunday attack were airlifted to Uganda on Wednesday for further treatment.

South Sudan's Health Ministry says at least 271 people were killed in Friday's clashes. The exact number of those killed in fighting since Sunday to Wednesday is not yet known.

There are fears that the war-torn country could descend into civil war again.

President Kiir and former rebel leader Machar have fought a civil war which broke out in December 2013 and left tens of thousands of people dead.

A peace deal signed by the two men last August under UN pressure led to the formation of a national government in April with Machar returning to his old post.

The local media reports show that the Monday evening ceasefire ordered by President Kiir and Vice President Machar was holding.

President Kiir directed all commanders to cease hostilities, control their forces and protect civilians.
