On June 30, 1967, in Geneva, Switzerland, Ambassador W. Michael Blumenthal, acting at the direction of the President, signed five multilateral agreements on behalf of the United States. He and the representatives of 45 other countries thereby concluded the Kennedy Round of trade negotiations and formalized an elaborate set of international obligations which, over a period of four years, would see the most extensive liberalization of trade ever achieved through co-operative action on the part of the trading countries of the world.
