ByJohn S. McClenahen The U.S.-Central America Free Trade Agreement (CAFTA) is scheduled to be signed May 28 at the Organization of American States building in Washington, D.C. Robert B. Zoellick, the U.S. Trade Representative, is scheduled to sign for the United States, and the trade ministers of Costa Rica, El Salvador, Guatemala, Honduras and Nicaragua are slated to sign for their nations. However, the pact will not be submitted immediately to Congress for approval or rejection. Consultations with Congress about including the Dominican Republic in CAFTA are not yet complete, and the Bush Administration announced on May 13 that it intends to submit a single legislative package that includes the Dominican Republic and the other Central American nations.
