Sabir Mohamed Hassan

Sabir Mohamed Hassan, Khartoum's chief negotiator on economic issues, speaks during a press conference in Khartoum on Jan. 15, 2012, prior to next weeks talks with South Sudan aimed at resolving a fierce dispute over oil compensation fees. Although most of Sudan's oil is produced in the south, for now it can only be exported via the north, and the two countries disagree over how much South Sudan should pay for the use of the north's pipeline and export infrastructure.
