克林顿将敦促南苏丹解决与苏丹的分歧

U.S. Secretary of State Hillary Clinton has arrived in South Sudan, where she is expected to push for compromise between the world's newest country and Sudan.

Clinton is meeting Friday with South Sudan President Salva Kiir in Juba during the brief visit.

Sudan and South Sudan failed to meet a United Nations August 2 deadline to settle differences on citizenship, oil revenue, and border demarcation that remain unresolved 13 months after the two nations split.  The diplomatic failure could expose both nations to economic sanctions.

A U.S. State Department official traveling with Clinton on her multi-nation African tour said the bitter divisions over territory and oil threaten to wreck the economies of both nations.
