Leaders of the Warsaw Pact called Saturday for multinational talks this year on reductions of conventional arms in Europe and separate negotiations on the elimination of short-range nuclear weapons from the region.
Concluding a two-day summit conference here, the seven-nation alliance also formally endorsed a platform of proposals on conventional arms reduction that Soviet leader Mikhail Gorbachev presented to President Reagan at their Moscow meeting in May.
The Eastern Bloc leaders stopped short, however, of formalizing several mutual security proposals made by Gorbachev earlier this week and of declaring a unilateral withdrawal of Soviet troops from Hungary, as had been expected by U.S. officials.
Three communiques emerged from the conference, but none made mention of Gorbachev's suggestion for a pan-European conference on conventional arms reductions, or his offer to cut Soviet aircraft deployed in Eastern Europe if the NATO alliance cancelled its planned redeployment of 72 American F-16 fighter planes from Spain to Italy.
Polish officials said the idea of a withdrawal of 65,000 Soviet troops from Hungary, which had been publicly supported in recent statements by senior Hungarian officials, was not even discussed at the session, although there had been a general discussion about eventual reductions in the number of Warsaw Pact troops.
Jerzy Nowak, a Polish foreign ministry official, said that for now the Warsaw Pact's position was that any unilateral withdrawal of Soviet troops from Eastern Europe would be carried out only as part of an agreement under which NATO would also make reductions of arms.
The lack of new initiatives by the Warsaw Pact summit could strengthen speculation about growing differences among Eastern Bloc leaders on both domestic and foreign policy. Romania, which has seemed lukewarm about Soviet arms control proposals, is also engaged in an open feud with Hungary over treatment of the Hungarian minority population in Romanian-ruled Transylvania.
Henryk Jaroszek, a Polish official serving as secretary general of the Warsaw Pact, said at a Saturday news conference that "exchange of information and views" on domestic matters "occupied an unusually important place" during the talks.
He added that the Romanian-Hungarian dispute had not been discussed and that protocol prevents the leaders from commenting on the affairs of other countries.
