 Conflict burst into the open after John R. Bolton, the American ambassador to the United Nations, scheduled Security Council briefings on two volatile issues that many on the 191-member General Assembly believe are their responsibility and two United States congressmen wrote an accusatory letter to Ambassador Dumisani S. Kumalo of South Africa, head of the Group of 77, which represents 132 developing nations.
