Security Council envoys pushing for an end to the Democratic Republic of Congo's almost three-year-old war are praising Congolese President Joseph Kabila for taking steps to resolve the conflict. Delegation chief Jean-David Levitte of France poke to reporters after talks with the president Friday in Kinshasa. He said Mr. Kabila impressed the 12-member U. N. team with his statements and his answers to their questions. Ambassador Levitte also said Mr. Kabila's decision Thursday to end a ban on political parties will help set up a national dialogue between Congolese political forces as called for in the Lusaka peace accords. Mr. Kabila became head of state in January, following the assassination of his father, then-President Laurent Kabila. Following the Kinshasa talks, the U. N. delegation left for Luanda for talks with Angolan President Jose Edu-ardo Dos Santos, who has given military backing to the Congolese government.
