The Men's 1000 meters event was marred by controversy. During the semifinals, Hwang Dae-heon of South Korea was disqualified for an "illegal late pass causing contact", and Lee June-seo of South Korea were penalized for a lane change that caused contact, allowing Li Wenlong from China to qualify for the A final joining two countrymen. Then, after the conclusion of the A final, Shaolin Sandor Liu of Hungary was disqualified for a "straight lane change from inside to out causing contact” and an “arm block at the finish", resulting in Ren Ziwei and Li from China being awarded the gold and silver medals respectively However, the
Korean Sport & Olympic Committee later filed an official appeal with the
Court of Arbitration for Sport over the disqualification of two of the South Korean athletes from the men's 1000 metres speedskating event semifinals. ==References==
