The United States will make another attempt next week to speed up the newly stalled multilateral trade talks in hopes of reaching an agreement by the scheduled Dec. 15 deadline.

In a visit billed as "President Carter's request," White House trade negotiator Robert S. Strauss will visit key leaders on how to get negotiating four European capitals to confer with momentum going again.

Strauss will leave Wednesday and return next Friday night. He will travel to Paris, Brussels, Copenhagen and Bonn, meeting, among others, with West German Chancellor Helmutt Schmidt.

The trip is part of a U.S. effort to assuage European displeasure over recent congressional trade actions and to try to work out a compromise on the issues of subsidies and counter-vailing duties.

Strauss said in a statement "a solution must be found" to the U.S.-European disagreements involving subsidies and countervailing duties if negotiators are to meet their Dec. 15 deadline.

The trade talks have bogged down in the past few weeks, mainly because West Germany, Denmark and Italy have taken offense at Congress' failure to extend countervailing duty waiver authority that expires early in January.

Both houses of Congress approved the legislation spearately, but the measure slipped through the cracks in the closing days of the 95th Congress. Key congressional leaders have pledged to push it through early next year.

If the waiver authority is not extended, Carter will be required to impose stiff penalties on certain foreign imports found to be selling here at below the prices charged at home. The prospect has sidetracked the talks.

Strauss already had been scheduled to travel to Europe Nov. 15 through 17 to put the finishing touches on the trade agreement in time to present it to the European Common Market's leadership Nov. 21.

However, unless Strauss can get the talks moving again this time, negotiators say the agreement could be delayed.
