Central Asian games is bigger BS. I think they only had it 4-5 times in its entire history. Sergey competed in the one that was cancelled the year before. He competed in 2003 and they never had one again until 2021. I think he fought one guy for the medal.
Kharitonov qualified for Olympics by winning silver medail in Asian boxing championships (entire Asia) in Phillipines in january of 2004, not by Central Asian games.
