The pope was scheduled to visit the country last year but shelved the plan until further notice.
President Kiir on Sunday returned to his capital Juba from Rome where he met with Pope Francis at the Vatican and briefed him on the implementation of the revitalised peace deal, which is already six months behind schedule.
The South Sudanese leader also met with the Vatican Secretary of State, Cardinal Pietro Parolin, who was accompanied by Archbishop Paul Gallagher, Vatican Secretary for Relations with States.
Speaking to reporters upon arrival at the Juba International Airport, Minister in the Office of the President, Mayiik Ayii Deng said Pope Francis has owed to pray for the people of South Sudan and the peace process.
Mayiik further said Kiir assured Pope Francis that the revitalised peace agreement will be implemented to its letter and spirit.
“The president assured the Holy Father that this peace is irreversible… The only problem facing him is the funding gap for the implementation of the peace agreement that’s why they are seeing some delays,” he explained.
According to Mayiik, President Kiir has urged Pope Francis to encourage international donors to contribute to the funding of the peace implementation.
“The president explained to the Holy Father his tour of Bahr el Ghazal and is going to tour the rest of the country soon to educate people about peace” he said.
“If the president did not believe in those things, he would not have gone to the highest moral authority in the world to tell him that the peace is implementable,” he added.
He revealed that a Vatican delegation will arrive in Juba on Thursday.
“They are coming for five days. I believe they are coming to see the situation by themselves,” he said.
Mayiik said Kiir met with the Vatican Secretary of State and talked about the issue of refugees and internally displaced persons and the need for support.
