On 21 March 1969, Soviet Premier Alexei Kosygin tried to phone Mao with the aim of discussing a ceasefire.[30] The Chinese operator who took Kosygin's call rather rudely, called him a "revisionist element" and hung up.[30] Zhou, who wanted to take up Kosygin's ceasefire offer, was shocked by what he regarded as Mao's recklessness: "The two countries are at war, one cannot chop the messenger."[30] Diplomats from the Soviet embassy in Beijing spent much of 22 March in vain trying to get hold of Mao's private phone number so that Kosygin could call him to discuss peace.
