A summit of world leaders has opened at U.N. headquarters with President Bush and Secretary-General Kofi Annan urging United Nations members to implement sweeping U.N. reforms.
President Bush called for stronger efforts to make the world body free of corruption, and said U.N. human rights bodies cannot include what he called "notorious human rights abusers."
Mr. Annan said a document on U.N. reforms the leaders plan to adopt is a "good start," but added that the world body has not achieved the fundamental reforms many believe are required.
The document -- approved Tuesday by the General Assembly -- is considered a watered-down version of far-reaching proposals Mr. Annan set forth earlier this year.
In his speech Wednesday, Mr. Annan said it was inexcusable that members could not to agree on measures aimed at nuclear disarmament and non-proliferation.
The summit, which is taking place during the United Nations' 60th General Assembly, will bring together heads of state and government from some 150 countries around the globe.
