Kinshasa has praised Kigali for announcing a unilateral ceasefire by its pro-rebel troops in the Democratic Republic of Congo, calling it a "first step in the right direction".
The Congolese Foreign Minister, Mr Abdoulaye Yerodia, speaking late on Sunday, two days after Rwanda called the unilateral cessation of hostilities, said the next step should be the "evacuation of occupied territories" by foreign troops in the east of the sprawling former Zaire.
Troops from Rwanda, Uganda and Burundi are in the Congo backing a rebellion that broke out in August 1998, fighting government forces supported by troops from Angola, Zimbabwe and Namibia. Chadian troops backing President Laurent Kabila have been withdrawn.
Mr Yerodia cited a UN Security Council resolution adopted in April deploring the presence of foreign forces in the country and calling for an immediate ceasefire.
He added: "If [the Rwandans] unilaterally declare a ceasefire, they can break it unilaterally, just as they began the war unilaterally. So let them come out of their unilateralism and enter into negotiation."
