Objective take here: He is 100% Asian, that is where he is from geographically. He has grown playing on APAC servers and has been formed there which makes him an APAC talent.
That being said, being asiatic ≠ being from APAC, there are plenty of parts of Asia that are not included in APAC such as the Middle East, China, or indeed, Far East Russia. In eyes of Riot he is an EMEA player, and here in the confirmation by the PRX CEO if people still wanna argue that https://twitter.com/nikhathi/status/1638512166063177731?s=46&t=Ktss9BR_J0-IBa79hzZ4iA
Conclusion: Geographically from the Asian part that belongs to EMEA, therefore, APAC talent but EMEA player.
