U.S. Trade Representative Carla A. Hills yesterday said there is only a 25 percent chance of reviving the global free-trade talks that collapsed last week, despite President Bush's statement earlier in the day that he would meet with his top trade advisers in an effort to revitalize the negotiations.

In London, the new British prime minister, John Major, was reported ready to present ways to get the trade talks back on track when he sees Bush in Washington next week, Reuter news service reported government officials as saying.

The talks collapsed Friday after the 12-nation European Community, Japan and South Korea objected to demands by the United States and Third World nations that they dismantle the barriers they have erected to food imports and dramatically reduce the subsidies they pay to their own farmers to grow and export crops. The dispute prevented a successful conclusion to the talks, which aimed to modernize and liberalize the rules governing world trade, known as the General Agreement on Tariffs and Trade (GATT).

Hills made her prediction in a meeting with her trade agency, aides said. It was the same gloomy prognosis that she presented Friday night in Brussels to representatives of U.S. industries and farm groups who were at the trade talks. She said then that the United States would not resume the talks until the EC is ready to negotiate specific commitments to reduce the $12 billion in subsidies that it pays its farmers to win world markets.

But White House spokesman Marlin Fitzwater said that Bush, who made the successful conclusion of the Uruguay Round of free-trade talks his top trade priority, wants to meet with his advisers later this week to see "what could be done to try to reinvigorate the talks."

Hills's staff, meanwhile, braced for an avalanche of trade complaints from U.S. industries that it fears will accompany the breakdown of the talks. Many of these complaints have been put off for years with the promise that a successful conclusion of the trade talks would settle the differences.

"I think everyone is going to give us 24 hours and the {complaints by industries of unfair trade practices by other countries} will start coming in," one trade official said.

Chief among them are likely to be complaints against Japan and South Korea for their bans on rice imports. U.S. rice growers and processors filed a complaint against Japan three years ago, but it was rejected in 1988 after Japan promised to put its agriculture policies on the table for the Uruguay Round.

Negotiations start today in Tokyo on a long-simmering dispute with Japan over allowing foreign companies access to public works projects and next week in London on another long-standing battle, this one with the EC over European subsidies to Airbus Industrie, the European plane maker that competes directly with Boeing Co.

Both negotiations are likely to be affected by the collapse of the talks last week, industry and U.S. trade officials said, as will a visit to Washington next week by a senior Korean envoy to explain his country's campaign against purchases of foreign goods.
