Soviet President Mikhail Gorbachev met Wednesday with former U.S. Secretary of State Henry Kissinger, the official Soviet news agency Tass said. Kissinger was in Moscow for a meeting of the Trilateral Commission, along with former President Valery Giscard d'Estaing of France and former Prime Minister Yasuhiro Nakasone of Japan. The 15-year-old commission is a private group of business, government, labor and academic leaders. Tass said that Gorbachev and Kissinger discussed "some considerations on the development of Soviet-American relations, which were set forth by Kissinger on behalf of President-elect George Bush." A senior official in Bush's transition office said that Kissinger was not an emissary but, speaking on condition of anonymity, added: "We expect him to pass along greetings from the president-elect."
