The National Dialogue Steering Committee – tasked with leading consultations to restore peace in the country – put pressure on the Media Authority to lift the ban.
“They are going to allow any journalists to come. They were preventing some journalists because they said some journalists are fond of criticism of what is happening in the country,” said Alfred Taban, the committee’s chief of media affairs.
Alier told the radio station: “You need to respect also the country, you can’t just label the country as crazy.”
Taban said Alier had since “promised that he will facilitate entry to the foreign journalists.”
The civil war that began in South Sudan in December 2013, when President Salva Kiir fell out with his former deputy Riek Machar, has been characterised by ethnic massacres, attacks on civilians, widespread rape, the recruitment of child soldiers and other forms of brutality and human rights violations.
Both government and rebel forces are accused of what many commentators regard to be war crimes.
According to the Foreign Correspondents’ Association of East Africa, journalists from leading news organisations – most of whom had previously reported in South Sudan – have been refused visas or accreditation over the past six months.
Last month Al Jazeera English staff were banned from working in South Sudan after airing a report from a rebel-held part of the country.
