The border and other issues, including how to share oil wealth between the two Sudans, have been hot-button, unresolved issues for Juba and Khartoum since the south became independent from Sudan in July 2011. In January 2012, South Sudan shut down oil production -- a key source of revenue for the south and north -- amid a dispute with the north over fees to transport crude from the south to export terminals in the north, via pipelines controlled by Sudan. In April last year, the south seized control of the border town of Heglig, nearly plunging the two countries back into war. The once-unified Sudans fought a 22-year civil war that ended with the signing of a comprehensive peace agreement in 2005.
