Khartoum accepts UN force

In a strange, and so for unexplained, turn of events, the Sudanese government has changed its mind, deciding to accept, "in principle," a joint United Nations and African Union peacekeeping force into Darfur.

Maybe it's cynicism, but I keep thinking to myself that there must be a catch somewhere, because up to now, Khartoum has successfully staved off an attempt led by the US to send peacekeepers to Darfur. Maybe China or Russia decided that to apply some pressure for some reason unknown to me. I can't imagine that either Moscow or Beijing have been too terribly concerned about how Khartoum's genocidal regime has reflected on them.
