The Olympic Winter Games in Sarajevo, Yugoslavia, are two years away, but officials of the Sarajevo Olympic Organizing Committee said yesterday they already have raised 80 percent of the $165 million needed and that facilities are either completed or that construction is on schedule.

In the United States for media briefings and meetings with potential contributors, Anton Sucic, mayor of Sarajevo and president of its Olympic Committee, said most ski trails are already being used for European championship events.

"We are following the plan we made many years ago," Sucic said through interpreter Pavle Lukac, press and public relations director for the Games.

Transportation, sewage and hotel facilities in the ancient Yugoslavian city are being improved, he said. A slalom stadium has been built. One million square meters of ski trails have been cut. Work is underway on a bobsled run and a ski jump area. Two arenas for figure skating and ice hockey and a speed skating oval are being built.

All events will be held at one of six sites within 30 kilometers of Sarajevo, in the Yugoslavian mountains where midwinter temperatures average 29 degrees. The Games will open Feb. 8, 1984 and close Feb. 19.

After yesterday's media briefing in Washington, Sarajevo officials were to fly to Los Angeles, site of the 1984 Summer Olympics, to meet with the Los Angeles Olympic Organizing Committee.

Much of the money has come from the Yugoslavian government, Lukac said. But the committee is seeking about 30 American corporate sponsors to purchase rights to use the Olympic logo in advertising and the right to sell their products at the Games. Coca-Cola, Miller High Life Beer, Kodak and U.S. Tobacco are among American sponsors so far.

In response to media questions, the officials said they expect no political problems.

"We hope to be a breaking point away from politics in the Olympic movement," Lukac said.
