KYOTO -- A two-day conference on reforming the United Nations ended here Wednesday with participants agreeing that the number of Security Council seats should be expanded to better meet threats to global security.

But the participants did not agree on what types of threats should receive the greatest attention.

Though the talks were unofficial, the recommendations will be used for reference next week in Vienna by a formal committee appointed by U.N. Secretary General Kofi Annan last year to examine ways to restructure the United Nations.
