They also agreed to form joint teams under the auspices of UNV to verify the absence of troops from both sides of the border.
This came after a meeting of the joint security and political committee of the two countries started on Monday in the Sudanese capital.
The talks were led by Sudan’s joint chief of staff, Kamal Abdo Moaroff and South Sudan’s Defense minister Koul Manyang Juuk.
“We look forward to a close relationship through the opening of border crossings and subsequent measures to take care of the common interests of the two countries’ peoples”, said Abdo al-Marof.
On his part, the South Sudan Defense minister claimed his country is keen to implement the agreement to promote stability on both sides of the border.
He pointed to “the importance of opening the border especially in light of economic crisis facing the two countries”.
South Sudan separated from Sudan in 2011 and took with it nearly 75 percent of oilfields.
Since then the two countries regularly accused each other of backing rebels of both sides and closed their border severally.
The latest was in 2017, when Sudan closed its border with South Sudan, saying it was meant to prevent arms-smuggling.
