Sixteen men's teams and sixteen women's teams will compete at the tournament - as well as the mixed shoot-out contest - hosted by FIBA in cooperation with the Malaysian Basketball Association (MABA) and organised by NBL Asia. It will be staged in the Gem-In shopping mall. Every game will be played on the same court.
Last year, the Gem-In shopping mall already played host to the competition and Japan's women and Qatar's men took home the trophy.
All eligible Asian National Federations were invited to register a team for the competition.
Bahrain, Turkmenistan and Jordan will make their debut at the event.
Men: Bahrain, China, Chinese Taipei, India, Indonesia, Japan, Kazakhstan, Kyrgyzstan, Lebanon, Malaysia (hosts), Philippines, Qatar, Singapore, Sri Lanka, Turkmenistan and Vietnam.
Women: Bahrain, China, Chinese Taipei, India, Indonesia, Japan, Jordan, Kazakhstan, Kyrgyzstan, Lebanon, Malaysia (hosts), Philippines, Singapore, Sri Lanka, Turkmenistan and Vietnam.
With 16 teams per gender registered for the competition, the 6 lowest-ranked teams in the FIBA 3x3 Federation Ranking at the 1 November 2016 cut-off date (except the hosts) will play a qualification in the morning of 26 May 2017. Teams will be divided into pools of 3 teams with the winner of each pool advancing to the FIBA 3x3 U18 Asia Cup 2017.
The event will then be played with 12 teams per gender, divided into 4 pools of 3 teams. The pools will not be determined through a draw, but will be automatically created, based on the 3x3 Federation Ranking of the participating countries as of 1 March 2017.
The top 2 teams from each pool will then qualify to a knock-out phase starting from the quarter-finals.
