Speaking at a banquet held at the Romanian embassy in Beijing on 23 August 1968, Zhou denounced the Soviet Union for "fascist politics, great power chauvinism, national egoism and social imperialism". He went on to compare the invasion of Czechoslovakia to the Americans in the Vietnam War and more pointedly to the policies of Adolf Hitler towards Czechoslovakia in 1938 to 1939. Zhou ended his speech with a barely veiled-call for the people of Czechoslovakia to wage guerrilla war against the Red Army.
