IMF, WORLD BANK TO MEET AMID NEW INFLATION FEARS Amid new concerns about inflation, interest rate increases and trade confrontations, finance ministers and central bankers meet next week to discuss a deteriorating global debt and economic situation. The meetings, under the auspices of the International Monetary Fund and World Bank, come as interest rates are turning higher and the already-weak dollar has sunk further, upsetting bond and stock markets. Uncertainty is growing about the vitality of the global economy and whether the heavily-indebted countries can continue to carry the burden of their growing debt without vast new assistance. Monetary and diplomatic sources said there are no signs any new debt initiative of the sort that Treasury Secretary James Baker unveiled 18 months ago in Seoul is in the works. The strategy has drawn a serious challenge from Brazil, which suspended interest payments on 67 billion dlrs of commercial bank debt last month. The Banks have responded by laying the groundwork for writing down Brazilian loans. Separately, French Prime Minister Jacques Chirac, in a visit earlier this week with President Reagan, sounded out the administration on a plan to funnel worldwide grain surpluses to the very poorest states. The French plan is certain to be discussed by the ministers in detail during next week's meetings and will undoubtedly be embraced by the developing countries. "There's interest on the part of some countries for looking at the support of the special problems of the very poorest countries, because their position is so extreme," a Reagan administration official said. He suggested Washington was open to disussing the issue. The meetings will also assess the success of the Baker debt initiative, which called for new funding to help debtor countries grow out of their problems. The largest industrial countries have been attempting to coordinate economic policy in the hope of controlling the decline of the dollar, U.S. trade and budget deficits and other problems. At the same time, the industrial countries see little evidence of a strengthening of economic activity and the Fund forecasts they will grow 2.5 pct. The United States sees 3.2 pct growth for itself, continuing its expansion for a fifth year, and has asked other industrial countries to stimulate their economies. These issues directly affect the debt problem and the ability of the debtor countries to grow out of their difficulties. In recent years, U.S. markets have absorbed the exports of developing country, allowing them to earn critical foreign exchange. But the United States wants to cut its trade deficit, running at a record 169.8 billion dlrs, and is pressing others to import more from developing countries. The discussions, from April six to 10, will be wide-ranging, touching everything from interest rates to the impact of development loans on the environment, according to monetary sources. The talks will include an examination of trade protectionist pressures in the wake of a decision by the Reagan administration to place some 300 mln dlrs in tariffs on microchip products from Japan, the sources said. The move accelerated the dollar's decline as financial markets grew alarmed that trade war was in the offing. There is concern that the action, prompted by U.S. charges that Japan has been selling computer chip products below fair market value and has kept its own market closed to imports, further undermining the international trading system. At the same time, the ministers will discuss the fundamental price weakness in basic commodities, the export mainstay of many developing countries. The so-called Group of Five industrial countries -- the United States, Japan, West Germany, France and Britain -- will gather for the first time since their February talks in Paris, where they agreed to keep the dollar from sliding further. The Five will be joined later by Italy and Canada for further debate on economic policy coordination. As part of the Paris accord, surplus countries such as Japan agreed to stimulate their economies, while America said it would reduce its federal budget deficit. Other major issues of the meetings include a U.S. bid to to have a larger say in approving loans of the Inter-American Development Bank, strengthening the link between loans and economic policy changes in debtor nations. Washington is also pressing the World Bank to take more account of the environment when making loan for dams and other projects. The new head of the Bank, Barber Conable, has said this issue is being reviewed and will be part of a reorganization plan for the Bank, now being prepared.
