From July 15 to the end of October 1963, Soviet newspapers, magazines and radio issued and broadcasted over 1,100 anti-China articles, of which an open letter from the Central Committee of the CPSU revealed the dispute between the Communist Parties of the two countries.
In light of the situation, from September 6, 1963, to July 14, 1964, the CPC Central Committee, in the name of the editorial departments of People's Daily and Hongqi (Red Flag) magazine, issued nine commentaries, including "Roots and Evolution of Divergence between Leaders of the CPSU and Us," which reviewed differences between both sides since 1956 and criticized leaders of the CPSU. From then on, the dispute between China and the Soviet Union turned white hot.
