REAGAN URGES FULFILLMENT OF EXCHANGE ACCORDS President Reagan, preparing to depart for the Venice economic summit on Wednesday, said the United States and its allies must fulfill agreements on exchange rate stability. "Economic policy decisions made last year in Tokyo, and at this year's meetings of Group of 7 Finance ministers in Paris and in Washington, cannot be ignored or forgotten," he said. "The commitments made at these meetings need to be translated into action," Reagan said in a pre-summit speech celebrating the 40th anniversary of the Marshall Plan.
