Soviet leader Mikhail Gorbachev congratulated President Bush and told him renewed efforts could bring them closer to "the solution to the most painful problems of the present time," it was disclosed Saturday.

Bush aides said Gorbachev made the remarks in a letter hand-delivered by Soviet Ambassador Yuri Dubinin to the new president's designated national security adviser, retired Lt. Gen. Brent Scowcroft, Friday afternoon.Bush told reporters at the White House Saturday morning that he would respond promptly and personally to the "nice, very generous letter, a letter pledging, you know, to work for world peace."

Bush has stressed recently he will not be rushed into deeper negotiations toward a Strategic Arms Reduction Treaty until his own administration can review the record compiled under President Reagan. He struck a similarly cautious tone toward U.S.-Soviet relations throughout his 1988 campaign.
