The Chinese Olympic Committee last night said it would support postponing or moving the 1980 Olympic Games in Moscow this summer.

The People's Republic of China only recently was readmitted as a participant in the Olympics.

Li Meng Hua, vice president of China's Olympic committee, told a news conference that "The Soviet military intervention in Afghanistan has met with strong opposition in the world, and the Chinese people strongly resent this aggression," the Associated Press reported from Lake Placid, N.Y., site of the Winter Olympics.

Meanwhile, the U.S. government does not want the Summer Games to be held in Moscow, but is not anxious to have them here, either, according to Nelson Ledsky, deputy assistant secretry of state for congressional relations and head of the State Department's Olympic task force.

He testified before the House subcommittee on transportation and commerce yesterday, saying that if the Games are moved from Moscow or if alternate games are organized, "it is our preference that they not be held in the United States."

Ledsky said that the State Department had been in contact with Canada and Australia about hosting the games in their entirety, and with Britain and some Third World nations about serving as partial hosts, should events be split up.

Mexico City, which hosted the 1968 Summer Olympics, and Munich, which hosted the 1972 games, have taken themselves out of consideration.

Ledsky said, "If no other countries come forward, we are prepared to serve as host."

Los Angeles, which is scheduled to host the 1984 summer Olympics, would be the most likely U..s site.

Ledsky said, as others have before, that the administration would be willing to provide financial assistance to a new host country but added that it would be premature to discuss what that financial committment might be.

Col. F. Don. Miller, executive director of the U.S. Olympic Committee (USOC), told the subcommittee which would have to approve any federal aid authorization, that it would cost in the neighborhood of $250 million to $300 million to organize an alternate Olympics, "depending on the site, what facilities were existing and how many countries were participating."

One administration official called this "a realistic figure" for the total cost but not a realistic estimate of what the U.S. government would have to spend.

"It is conceivable that we will have to ask for several million to help fund alternate games," he said, perhaps somewhere around $15 million.

Some administration officials say they believe that Los Angeles would be the easiest and least expensive site for an alternate Olympics, since there are already existing athletic and housing facilities at USC and UCLA which could function as an Olympic village. But they are not anxious to have the games on American soil.

"I'm not saying it would be provocative to have them here," Ledsky said. "I don't think it would be. But our chances of building support are greatly enhanced if the site is outside the United States."

Lloyd Cutler, president counsel, said on Sunday, "It may be that the best site would be outside the U.S., so that it was not a contest in that sense between the U.S. and the Soviet Union."

The administration is anxious to avoid not only the us-against-them mentality, one official said, but also "the charge that we're in this for a selfish motive."

Ledsky also testified at the hearings that "there would be no legal sanctions," against American citizens, athletes or spectators who wanted to go to the games in Moscow next summer should they take place. "We do not intend to enforce a requst by denial of passports to individual Americans," he said.

Lake Placid will be minus its most famous spectator when the Winter Games open there in two weeks. President Carter, who was scheduled to act as official host at the opening ceremonies, will remain in Washington because of the continuing international crisis. Vice President Mondale will replace him.
