LATIN, CARIBBEAN NATIONS OPPOSE TRADE BILLS A group of Latin American and Caribbean nations formally opposed trade legislation pending in Congress, saying it would curb their exports, slow development and hinder its ability to repay foreign debt. Mario Rodriguez Montero, president of an Organization of American States special committee on trade, said he was aware of the large U.S. trade deficit, but added "the region should not be the one affected by the trade bills." He said the causes of the deficit were the strong dollar and the budget deficit, and "it is regrettable to solve it by a trade bill that would only serve private U.S. interests." Rodriguez made the comment at a news conference after two days of meetings with U.S. officials on trade bills now in Congress that are designed to reduce the U.S. trade deficit, which last year hit a record 166.3 billion dlrs. Congressional observers say the bills are aimed mainly at Japan, Taiwan, South Korea and a few other nations with large, annual trade surpluses with the United States. Mexico, Brazil and Venezuela are the only Latin nations with large trade surpluses last year with the United States, but even Mexico, with the largest, had a surplus of only 5.2 billion dlrs, against Japan's of 58.6 billion dlrs. The European Community has also opposed the bills. Rodriguez said the Latin and Caribbean nations backed the Reagan Administration's opposition to many of the sections in the legislation, including those to curb imports and to require retaliation for foreign unfair trade practices. He told reporters the committee would likely mount a campaign to fight the legislation when it comes up for debate on the Senate floor, expected next week. Rodriguez said "the region needs trade to continue development. We hope this need will not be affected negatively by trade legislation." Rodriguez said: "we need to keep the market opens - especially the U.S. market - to obtain the necessary foreign exchange not only to service the debt but also to continue national development progress." President Reagan has said he would veto any legislation he termed "protectionist," and his aides now are mounting a effort to water down some of the objectionable provisions in the legislation. Asked whether Reagan was ready to cast a veto, Rodriguez said as yet "the administration is not in a veto frame of mind."
