President Vladimir Putin has urged U.S. businessmen to use their influence to help normalize Russia-U.S. relations.

Speaking at an economic forum in St. Petersburg, Putin said relations between Moscow and Washington are now at their lowest point since Cold War times.

During a panel meeting, Putin called on the U.S. participants of the forum to "help restore a normal political dialogue ... help a newly elected president and new administration."
