Depiction: A crowd of people march with a banner reading "Foreign experts and students say: No Nukes." Chinese letters are also on the banner. Photo caption reads: A small group of foreign residents and students march outside the Soviet embassy in Peking Wednesday to protest the arms race between the US and USSR. Escorted by hundreds of police, the placard-bearing marchers attempted to present letters urging disarmament to officials at the embassies of both nations without a great deal of success.
