Sudan's foreign minister and Chinese leaders have discussed an oil transport fee dispute with South Sudan and the security of Chinese workers.
Sudan Foreign Minister Ali Ahmed Karti wrapped up a two-day visit to Beijing, asking China for help negotiating oil transport fees with newly independent South Sudan.
An agreement that would require oil-rich South Sudan to pay fees to transport its oil through the north broke down after Khartoum began confiscating oil from the South.
In response, South Sudan cut its oil supplies to the north. Karti asked Chinese Vice President Xi Jinping for help in mediating the dispute.
