Spring. Speaking at a banquet at the Romanian embassy in Beijing on 23 August 1968, the Chinese Premier Zhou Enlai denounced the Soviet Union for "fascist politics, great power chauvinism, national egoism and social imperialism", going on to compare the invasion of Czechoslovakia to the American war in Vietnam and more pointedly to the policies of Adolf Hitler towards Czechoslovakia in 1938–39. Zhou ended his speech with a barely veiled call for the people of Czechoslovakia to wage guerrilla war against the Red Army. The next day, several countries suggested a United Nations resolution condemning the intervention and calling for immediate withdrawal. Eventually, a UN vote was taken with ten members supporting the motion; Algeria, India, and Pakistan abstained; the USSR (with veto power) and Hungary opposed. Canadian delegates immediately introduced another motion asking for a UN representative to travel to Prague and work toward the release of the imprisoned Czechoslovak leaders. By 26 August a new Czechoslovak representative requested the whole issue be removed from the Security Council's agenda.

He also sought to re-centralize the economy, as a considerable amount of freedom had been granted to industries during the Prague Spring. Commentary on politics was forbidden in mainstream media, and political statements by anyone not considered to have "full political trust" were also banned. The only significant change that survived was the federalization of the country, which created the Czech Socialist Republic and the Slovak Socialist Republic in 1969. In 1987, the Soviet leader Mikhail Gorbachev acknowledged that his liberalizing policies of glasnost and perestroika
