[4] On 8 November 2012, the Olympic Council of Asia awarded the 2021 Asian Youth Games hosting rights to Surabaya, Indonesia.

Surabaya was an unsuccessful bidder for the then-2018 Asian Games when they were defeated by Hanoi, Vietnam.

Sri Lanka's replacement was set to be decided at an OCA general assembly scheduled in September 2015.
