The 1986 ABC Under-18 Championship was the ninth edition of the Asian Basketball Confederation (ABC)'s Junior Championship. The games were held at Manila, Philippines from December 28, 1986, to January 4, 1987.[1] Taiwan came to Seoul to participate the competition, but withdrew later due to the conflict about using the Chinese flag during the event.[2]
The games were held at Rizal Memorial Coliseum, located in Manila. On April 14, 1984, ABC Executive Committee had a meeting at the Walkerhill Hotel, Seoul and decided to hold the next event at Kuala Lumpur, Malaysia, but later changed to Manila, Philippines.
