‘Some Movement’ in Arms Talks

GENEVA —  The U.S.-Soviet arms negotiations broke for a summer recess today after seven weeks of talks that U.S. negotiators say brought signs of movement on strategic and space weapons.

“Important substantive differences” remain, chief U.S. delegate Max M. Kampelman told reporters after a final meeting before the summer break. Kampelman dismissed as propaganda a remark by Soviet delegation head Viktor P. Karpov that no noticeable progress was made. “There’s been some movement here,” the U.S. negotiator said.
