South Sudan's President Salva Kiir and his political opponent Riek Machar will have their assets frozen if they fail to stop fighting and killings in the country that has been in turmoil over the past one year.
Kiir and Machar will also be banned from travelling within the region, plus they will be subjected to an arms' blockade. They will also not access any supplies "that could be used in war".
These are the full list of sanctions that regional leaders have placed on the table to deter the two protagonists from breaking the ceasefire.
The Intergovernmental Authority on Development (IGAD) came to the decision after a two-day meeting in Addis-Ababa, Ethiopia.
"This conflict has to come to an end. We need to focus our attention and resources on development and not on endless conflicts," said President Uhuru Kenyatta, who has been the pointman in getting Machar and Kiir off the battlefields.
IGAD chairman Hailemariam Dessalegn, the Prime Minister of Ethiopia, hosted six other Presidents from the region, in talks that decided that Kiir and Machar have to agree on how to end the conflict and get a political deal.
Dessalegn, Kiir (South Sudan), Kenyatta (Kenya), Yoweri Museveni (Uganda), Ismail Guelleh (Djibouti), Hassan Sheikh Mohamud (Somalia) together with chairperson of the African Union commission Dr Nkosazana Dlamini Zuma granted Kiir and Machar 15 more days to go back and explain to their supporters why they needed to end the hostilities.
"The Parties commit to an unconditional, complete and immediate end to all hostilities, and to bring the war to an end, as of the date of this Resolution. The Parties further commit to the immediate cessation of the recruitment and mobilisation of civilians," the regional heads said in a joint communique issued Friday night at Addis Ababa.
The regional heads, who met together with key emissaries from the United Nations, China, Denmark, Japan, the European Union, the United Kingdom, the United States and Norway, also warned Kiir and Machar that the regional countries will step in at any time to quell the fighting.
"The IGAD region shall, without further reference to the warring Parties, take the necessary measures to directly intervene in South Sudan to protect life and restore peace and stability," the communique noted.
The IGAD bosses added: "Should it be necessary to implement these measures, the IGAD region calls on the Peace and Security Council of the African Union, the Security Council of the United Nations, and the entire international community, to render all possible assistance in the implementation of these measures."
