The Soviet Union soon will undertake a "radical review" of its foreign military assistance programs, a Soviet Communist Party official said yesterday.

Andrei S. Grachev, deputy of the international department of the Communist Party Central Committee, told reporters that Moscow is putting less emphasis on its relations with the Third World in light of political changes in Eastern Europe and at home.

He indicated that foreign military assistance programs could be readjusted as a result, the Associated Press reported.

"These will be subject to a very radical review in the near future," he said.

Grachev acted as moderator at the first in a series of meetings between U.S. journalists and Soviet political figures, scholars, writers and others who are here in connection with the U.S.-Soviet summit this week.

His comments about foreign military assistance were in response to a question about whether Moscow intended to reduce its aid to Cuba and other countries in light of its own domestic economic and political problems.

Grachev did not specifically mention Cuba, but his response seemed to indicate that a review of foreign military assistance would include all countries currently receiving such aid.

A U.S. Defense Intelligence Agency official told Congress last month that the Soviets already have been cutting back their military aid programs. The value of Soviet military assistance to Third World countries dropped to $17 billion in 1989, about $2 billion below the previous year's figure.

Lower shipments to Iraq and other Middle East states accounted for the drop, the official said.

Meanwhile, Soviet President Mikhail Gorbachev said in an interview published yesterday that the North Atlantic Treaty Organization and the Warsaw Pact -- the two alliances that shape the political map of Europe -- should be scrapped in favor of pan-European unity.

Gorbachev also told Time magazine that the United States wanted NATO to dominate a new unified Europe, and vowed the Soviet Union would never allow this, Reuter reported.

"We are already entering a new phase that should be characterized by the establishment of permanent security structures instead of NATO and the Warsaw Treaty Organization," he said.

"I envision Europe as a union of states with common insitutions," he said in the interview, conducted last week in Moscow.

President Bush's call for a "Europe whole and free" and the Soviet vision of a "common European home" strike a similar note, said Gorbachev. But he added, "There are some differences."

The United States wants NATO, strengthened by a unified Germany, to dominate Europe, said the Soviet leader, adding, "We will never agree to assign it {NATO} the leading role in building a new Europe."

The Soviet leader said the key to Europe's future is to introduce "totally new structures on a pan-European basis, naturally with the U.S. and Canada actively involved."
