25 teams took part in the competition, 3 of them in the Australasian Zone, 8 in the Asian Zone, 9 in the European Zone and 5 in the Pan American Zone. As defending champion, Malaysia received a bye through the zone qualifications and the first round of Inter-zone ties, and played directly in the second round of inter-zone ties (the semifinal round of the entire tournament).
New Zealand, led by the Purser brothers, Richard and Bryan, won the Australasian Zone for the first time by beating Australia (8-1) and Singapore (7-2). Denmark again prevailed in the European Zone. Its closest tie came in the zone semifinal against England which the Danes won six matches to three, thanks largely to Svend Pri's three victories. Three wins by Jamie Paulson were also instrumental in Canada's first ever victory (6–3) over the USA in the Pan American zone.
The greatest drama came in the Asian Zone which contained several of the strongest teams in the entire competition. Indonesia, fighting to regain the cup that it had relinquished in 1967, began its quest by defeating India (7-2). It then became embroiled in yet another highly controversial tie, but this time one in which Indonesia, rather than its opponent nation, claimed to be the victim of partisanship. Facing Thailand in Bangkok, up three matches to two, Indonesia removed its player (Muljadi) from the court during the first game of the sixth match and refused to continue. Though Thailand was initially awarded the tie, 6-3, the IBF upheld an Indonesian protest and ordered the tie to be continued, at three matches each in Japan, where the zone final was scheduled to be played. When Thailand refused to comply, Indonesia was awarded the match (6-3). In the zone final Indonesia faced a Japanese team which boasted one of the strongest lineups of singles players (Ippei Kojima, Masao Akiyama, and Junji Honma) in the tournament. Indonesia finally prevailed (5-4), largely because of Rudy Hartono's four victories.
The following teams, shown by region, qualified for the 1970 Thomas Cup. Defending champion and host Malaysia automatically qualified to defend their title.
