The Thaw became possible after the death of Joseph Stalin in 1953. First Secretary Khrushchev denounced former General Secretary Stalin in the "Secret Speech" at the 20th Congress of the Communist Party, then ousted the Stalinists during his power struggle in the Kremlin. The Thaw was highlighted by Khrushchev's 1954 visit to Beijing, People's Republic of China, his 1955 visit to Belgrade, Yugoslavia (with whom relations had soured since the Tito–Stalin Split in 1948), and his subsequent meeting with Dwight Eisenhower later that year, culminating in Khrushchev's 1959 visit to the United States.
