MOSCOW, June 11 (AP)—The Soviet Union today accused China of provoking new clashes on the Soviet border and said China possibly will make further efforts to “poison the good, business like atmosphere” at the international Communist conference. Soviet Foreign Ministry spokesman Leonid Zamyatin added that recent incidents “probably have the purpose of hampering the consultations proposed by the Soviet Government”. He was replying to a question on the Chinese Protest Note, delivered to the Soviet Embassy in Peking that accused Russians of killing a woman herder and kidnapping another herdsman. The Note claimed Soviet troops, tanks and armoured cars were involved in the incident which allegedly occurred in Sinkiang province.
