HELSINKI, Finland (AP) _ A court today sentenced two businessmen to 34 months in prison each after convicting them of treason for selling U.S. computer technology to the Soviet Union.

The court found Paavo Manner and Peter Perovuo guilty of acquiring high technology intended for both civilian and military use and exporting it to the Soviet Union in 1985 and 1987.

The businessmen were also fined $65,000. A third defendant was given a five-month suspended sentence as an accomplice.

The trial was conducted behind closed doors in the Helsinki Court of Appeals, which imposed a 25-year secrecy rule on the proceedings.

The court said the leak of classified material to another state could endanger Finland's relations to a foreign power.

The two men were arrested one year ago.

The equipment imported into Finland was subject to re-export restrictions, set by the 16-nation Coordinating Commitee for Multinational Export Controls, which are designed to prevent militarily useful technology from reaching Soviet bloc countries.
