Nigerian President Olusegun Obasanjo and Cameroon leader Paul Biya also agreed to negotiate a new date for Nigeria's withdrawal from the Bakassi peninsula.
Nigeria was set to hand over control of the oil-rich peninsula to Cameroon last September, under a 2002 ruling. But Nigeria missed the deadline.
In Wednesday statement, both presidents also welcomed progress already made in marking their 1,600 kilometer boundary.
While tension over Bakassi continues, the two nations have already exchanged several villages near Lake Chad.
Cameroon and Nigeria have fought for control of the peninsula, which, along with crude oil, consists of wetlands rich in fish stocks.
