The first government to offer an apology was Hungary, on 11 August 1989.
The Hungarian Socialist Workers' Party publicly published its opinion on the fundamentally wrong decision to invade Czechoslovakia.
The House of the National Assembly of Poland in 1989, on the 21st anniversary of military intervention, adopted a resolution condemning the armed intervention.
Another apology was issued by the People's Assembly of East Germany on 1 December 1989, where they apologized to the Czechoslovak people for their involvement in the military intervention.
An apology from Bulgaria came on 2 December 1989.

On 4 December 1989, Mikhail Gorbachev and other Warsaw Pact leaders drafted a statement calling the 1968 invasion a mistake.
The statement, carried by the Soviet news agency Tass, said that sending in troops constituted "interference in the internal affairs of a sovereign Czechoslovakia and must be condemned."
The Soviet government also said that the 1968 action was "an unbalanced, inadequate approach, an interference in the affairs of a friendly country".
Gorbachev later said that Dubček "believed he could build socialism with a human face.
I have only a good opinion of him."

This acknowledgement likely helped to encourage the popular revolutions that overthrew Communist regimes in East Germany, Czechoslovakia, Poland, and Romania at the end of 1989 by providing assurance that no similar Soviet intervention would be repeated were such uprisings to occur.

The invasion was also condemned by the newly appointed Russian President Boris Yeltsin ("We condemn it as an aggression, as an attack on a sovereign, stand-up state as interference in its internal affairs").
During a state visit to Prague, on 1 March 2006, also Vladimir Putin said that the Russian Federation bore moral responsibility for the invasion, referring to his predecessor Boris Yeltsin's description of 1968 as an act of aggression: "When President Yeltsin visited the Czech Republic in 1993 he was not speaking just for himself, he was speaking for the Russian Federation and for the Russian people.
Today, not only do we respect all agreements signed previously – we also share all the evaluations that were made at the beginning of the 1990s... I must tell you with absolute frankness – we do not, of course, bear any legal responsibility.
But the moral responsibility is there, of course".

On 23 May 2015, Russian state channel Russia-1 aired Warsaw Pact: Declassified Pages, a documentary that presented the invasion as a protective measure against a NATO coup.
The film was widely condemned as political propaganda.
Slovakia's Ministry of Foreign Affairs stated that the film "attempts to rewrite history and to falsify historical truths about such a dark chapter of our history."
František Šebej, the Slovak chair of the Foreign Affairs Committee of the National Council, stated that "They describe it as brotherly help aimed to prevent an invasion by NATO and fascism.
Such Russian propaganda is hostile toward freedom and democracy, and also to us."
Czech President Miloš Zeman stated that "Russian TV lies, and no other comment that this is just a journalistic lie, can not be said".
Czech Foreign Minister Lubomír Zaorálek said that the film "grossly distorts" the facts.
Russian ambassador to the Czech Republic, Sergei Kiselyov, has distanced himself from the film and stated that the documentary does not express the official position of the Russian government.
One of the most popular Russian journals, Gazeta.ru, has described the document as biased and revisionist, which harms Russia.
