JUBA, July 19 (Xinhua) -- South Sudanese President Salva Kiir on Thursday pledged to end the devastating war in his country as the warring factions continue with peace talks in neighbouring Sudan.

Speaking during the oath-taking ceremony of new foreign minister Nhial Deng Nhial in Juba, Kiir said he is ready to sign the agreement to bring peace to South Sudan.

"People of South Sudan are looking for peace and if that arrangement can bring peace to the people of South Sudan, I'm ready to take it," Kiir said.

Sudan is continuing with mediation efforts spearheaded by East African regional bloc the Intergovernmental Authority on Development (IGAD) in a bid to find political solution to the South Sudan conflict now in its fifth year.

The Sudanese mediation team on Tuesday extended the negotiations until Thursday after a section of the opposition rejected a revised power-sharing formula that called for creation of five vice presidents post in the unity government.

The negotiators said the warring factions are expected to sign the revised deal on July 26.

Though Kiir expressed concerns about some provisions of the proposed power-sharing deal, he promised to agree to an inclusive unity government.

"South Sudan has become a field of experiments. Things that have never been done in any government and in any country are being tried in South Sudan whether they work or they will not work," Kiir said.

"People talk about inclusivity. Nobody is going to be left out of the government," the South Sudanese leader added.

South Sudan descended into civil war in late 2013, and the conflict has created one of the fastest growing refugee crises in the world.

The UN estimates that about 4 million South Sudanese have been displaced internally and externally.
