TEHRAN, Iran (AP) _ Iran will take part in the World Cup Freestyle Wrestling championships in the United States next month, the Islamic Republic News Agency reported Sunday.

Iranian sports teams have visited the United States before, but such exchanges have been boosted by the success of the visit by U.S. wrestlers to Iran last month.

The wrestlers, who participated in an international tournament in Tehran, were the first American sportsmen to go to Iran since the Islamic revolution in 1979.

In April, the Iranian wrestling team will take part in the World Cup at Oklahoma State University, IRNA quoted the Iranian Olympic Committee as saying.

Iranian-U.S. relations have been hostile since the revolution overthrew the U.S.-backed shah. But Iran's President Mohammad Khatami, who took office in August, has been trying to engineer a detente.
