Sudan, South Sudan Sign Oil Deal

Significant land disputes, however, remain unsettled

KAMPALA, Uganda — The presidents of Sudan and South Sudan signed a long-awaited cooperation agreement on Thursday, paving the way for the resumption of oil exports and casting their ailing economies a desperately needed lifeline. But several analysts said the deal came up far short.

The status of Abyei, a contested border area, was not settled. Nor was that of several other disputed territories, differences that have driven the countries' two leaders, historic enemies, nearly to all-out war.
