Czech-Polish-Hungarian Accord Urged : Europe: Havel proposes ‘spirit of solidarity’ in aftermath of Soviet domination.

President Vaclav Havel of Czechoslovakia proposed Thursday that Poland and Hungary join with Czechoslovakia “in a spirit of solidarity” to help coordinate “a return to Europe” after decades of Soviet domination.

Addressing a joint session of the Polish National Assembly, the former dissident playwright praised Poles for leading the way to political reform in East Europe, commenting that “we remember you were the first.”

“From our joint ideals and joint experiences,” Havel said, “should come what you and I call the ‘return to Europe.’ We should coordinate this effort with our neighbors in Hungary, where I am going tomorrow.”

Havel, who was elected president last month after Czechoslovakia’s peaceful revolution in November, told the Polish lawmakers that a joint program by East European countries would help avoid fruitless rivalry among countries striving for integration with West Europe.

“We should not compete in who is going to overtake whom and who will first win a seat in some European body,” he said, “but we should do just the opposite: help each other in the spirit of that solidarity with which, in worse times, you protested against our repression and we against yours.”

Havel suggested that Poland and Hungary send representatives to Czechoslovakia to talk about what form their cooperation should take. This idea was seen as a response to Polish proposals to forge closer links with the Czechoslovaks.

The Poles are worried by the possibility of a united Germany with an enormous economic potential--a development they see as inevitable in coming years. Prime Minister Tadeusz Mazowiecki of Poland visited Prague on Wednesday to propose stronger economic, political and environmental cooperation between Poland and Czechoslovakia.

West Germany’s business interests in Poland and Czechoslovakia are growing. However, the Poles feel that Czechoslovak industry, generally regarded as being in better condition than Poland’s, has given the Czechoslovaks an economic head start.

Havel’s comments stopped short of a formal commitment to a special relationship with Warsaw. However, they indicated a willingness to discuss wider cooperation that would include Hungary, where the West Germans have also stepped up their business activities.

“Western Europe is much more advanced in integration processes,” Havel said, “and if we (East European nations) were to return to Europe individually, it would certainly take much longer and it would be much more complicated than if we act together. This does not only concern economics. It concerns everything, including disarmament talks.”

Havel said the fall of totalitarianism is providing a chance to fill a power vacuum in Central Europe that has existed since the fall of the Hapsburg Empire at the end of World War I.

“We have the chance in these countries that were colonized by the Soviet Union,” he said, “to join in a formation that would not present itself to rich West Europe as an impoverished relative or a helpless-looking amnestied prisoner--but as someone who can also contribute something to it.”

He said it is still difficult to tell what “institutional shape” Central Europe will take, adding: “We want to think about the coordination of our effort. . . .

“We want to belong to a Europe of sovereign states--not to be divided into pacts and blocs--a Europe that does not need the support of superpowers because it is capable of defending itself.”

A year ago, Havel was in jail in Prague, arrested for attending a rally to commemorate the suicide of a student who had set himself on fire to protest the 1968 Warsaw Pact invasion--with Polish army participation--that put down the so-called Prague Spring reform movement.
