The Polish leader, Gen. Wojciech Jaruzelski, will pay an official visit here in early March in his first trip abroad since he imposed martial law in Poland Dec. 13, according to Tass, the official Soviet news agency.
The announcement said Jaruzelski would lead a delegation of the Polish Communist Party and government officials in talks with Kremlin leaders.
East European diplomatic observers said the move appeared to reflect confidence by Polish authorities that the situation there has been brought under control and that closer consultations with the Kremlin were needed for assessing plans for a political resolution of the crisis.
Tass pointedly referred to Jaruzelski only by his civilian titles of first secretary of the Polish party and premier to suggest that he was not coming here as the head of the military council ruling Poland but as the leader of an allied party to inform Moscow about its political decisions.
The Polish Communist Party Central Committee is scheduled to meet Wednesday and Thursday--its first session since the imposition of martial law.
The plenum's decisions are expected to provide clearer indications as to the government's political intentions. But it is believed in well-informed circles here that Jaruzelski's position in talks with the Soviet leaders will be his often-stated claim that martial law cannot resolve Poland's social and political problems, but that it can create conditions under which they could be resolved by political means.
In this context, there appear to be slight differences of opinion between Moscow and Warsaw.
Soviet sources in private conversations have repeatedly maintained that martial law in Poland should not be lifted soon. This view is reflected in public commentaries and news dispatches tending to emphasize the effectiveness of the military government in restoring order and insisting that life in the country was returning to normal.
However, Poland's economic indicators for January do not suggest that the military authorities have revived the economy despite massive aid from the Soviet Union and other East European countries.
According to East European analysts, Jaruzelski is believed to have reached the stage at which the party has to establish a framework for resumption of a dialogue with Polish workers and the Roman Catholic Church.
The Polish Central Committee meeting may produce clearer Polish Communist attitudes on this issue, and Jaruzelski's trip is seen by Western observers as an effort to discuss them with Soviet leaders.
In this view, Jaruzelski delayed his visit to Moscow--a traditional ritual for a new Soviet Bloc leader--to come with a program backed by the Central Committee. The delay is believed also to have been motivated by efforts to avoid the appearance of being a Kremlin puppet.
An indication of Warsaw's attitude toward the independent trade union Solidarity was revealed yesterday in an article in Pravda written by Weslaw Bek, the editor-in-chief of the Polish Communist Party newspaper Trybuna Ludu.
Bek asserted that the Polish Communist Party "had never identified the mass rank and file of Solidarity with its extremist leadership" and that "it had led the fight for the trade unionist makeup of Solidarity."
Analysts here say the Soviets are opposed to resumption of talks with moderate Solidarity elements until the Polish party regains its strength.
