Back in summer of 2015 when I visited Stary Oskol for Russian Nationals I had the chance to film Oleg Chen a couple of days before he competed.
Update: Session Video
Oleg went 130kg in the Snatch and 140kg in the Clean & Jerk (his wrist bothered him).
More: read the Oleg Chen Interview here.
And here is Oleg competing a couple of days later, going 157kg + 185kg.
