TEHRAN, Young Journalists Club (YJC) - Kabila became Congo's leader in 2001 after the assassination of his father and by law could not run again after his mandate ended in December 2016.
But he has remained in office because of delays in holding elections, which sparked deadly protests.
He told the annual gathering of world leaders at the U.N. General Assembly on Tuesday that "everything will be implemented to guarantee the peaceful and credible nature of these elections ".
Kabila warned that the United Nations will not be "an organization for all if the intrusive interference of some governments in matters undoubtedly in the domestic policy of the states" continues. He did not name any countries.
He also called for an "effective and substantial" start to the withdrawal of the U.N. peacekeeping force in Congo.
