The United States and its industrial allies are trying to slow the development of missiles in Argentina, Brazil and North Korea and hope to have the cooperation of the Soviet Union in the global campaign against proliferation.

The State Department confirmed on Monday that the seven allies, meeting in Rome Sept. 8-9, exchanged expressions of concern about missile proliferation and technology transfers that might enhance Argentina's capability.Afterward, a U.S. official told The Associated Press the same group registered concern in its deliberations about programs in Brazil and North Korea.

The official, who spoke on condition of anonymity, said Secretary of State George P. Shultz may pursue the problem with Soviet Foreign Minister Eduard A. Shevardnadze during their talks in Washington on Thursday and Friday.

In any event, the official said, Assistant Secretary of State H. Allen Holmes will take up the issue at talks in Washington next week with Viktor P. Karpov, senior Soviet arms control negotiator.
