Background
The Philippines was supposed to host the FIBA World Championship in 1962 but FIBA revoked hosting rights after the government of then President Diosdado Macapagal, refused to grant visas to players and officials of socialists countries including Yugoslavia and the Soviet Union. A smaller tournament, the Spalding Invitation Tournament was held in the Philippines in its place. The FIBA World Championship was held in 1963 in Brazil. ==Competing nations==
