There will be at least one American participating in the Moscow Olympics. He is Mike Perry, coach of the Swedish basketball team.

"Mike will definitely be going to Moscow" a spokesman for the Swedish Basketball Association said yesterday.

Perry, of Kingson, N.Y., flew to Washington to get U.S. State Department permission for the trip last week. He is now in Poland with the Swedish team.

"The State Department was very disturbed that I was going to Moscow. If they could have, they would have stopped me," Perry reportedly told the association after his return.

Perry admitted to having doubts about his Moscow trip, according to the association spokesman.

"I have lain awake nights sometimes wondering whether it is right or wrong for me to go," the association quoted Perry.

"I naturally feel strong sympathy for other Americans, who after long, intensive training, have been obliged to stay home," Perry said. "I try to keep to the principle that sport and politics don't mix, although I realize it is a little naive in the present world situation."

Perry said he supported President Carter's decision to boycott the Olympics in protest against the Soviet intervention in Afghanistan.

But he said he thought Carter should have taken a softer line.

"I think Carter regrets that he said at the start of all this that America would on no account attend the Games," he said.

"He should have been a little softer in his approach and still made a strong protest. Now he has no possibility to take back what he said."

He said he realized that the Soviets might try to use his presence in Moscow for propaganda purposes.

Perry first came to Sweden in the mid-70s to train the Alvik basketball team. He later took over the training of the national side, and, after a break, took over as full-time coach two years ago.

The team returns from Poland July 15. After two days training in Stockholm, the Swedes leave for Moscow on July 18.

Perry says "with luck" Sweden may place fifth in Olympic basketball.

"If we do that, it will be the biggest-ever breakthrough for Swedish basketball," he said.

Lord Killanin, president of the International Olympic Committee, arrived in Moscow yesterday for the 22nd Olympic Games and urged reporters to concentrate on sports rather than politics during the next three weeks.

Killanin, speaking at an airport news conference, said he was dismayed about allegedly inaccurate stories he has been reading recently in the media.

"I would remind you, gentlemen, we are here for a sporting event to report about sports," Killanin said.
