Sudan's President Omar al-Bashir is in South Sudan's capital for talks aimed at improving relations, which have warmed since the countries nearly went to war last year.
Mr. Bashir was greeted at the Juba airport Friday by South Sudan's President Salva Kiir. The two men later held closed-door talks that Sudan's news agency says focused on implementing recent economic and political cooperation agreements.
South Sudan re-launched crude oil production last week, after a shutdown of more than a year prompted by what the south considered excessive fees to use northern pipelines.
The two countries have been at odds since South Sudan won independence from the north in 2011, after decades of civil war. Their armies clashed along the border last year amid escalating disputes over the pipeline fees, border demarcation, and which side controls revenue-producing oil fields.
