the early years of the competition as the country conquered the 1956 and 1960; this remains as South Korea's best achievements in the tournament. West Asian domination (1964–1988) After Hong Kong and South Korea hosting the two first editions, Israel was chosen as hosts of the 1964 AFC Asian Cup. Using the same format of the two previous editions, this tournament only had four teams and played in one single group to determine the champions.
