The 23-year-old clocked a time of 41.175sec in the A final to beat nearest challenger Abzal Azhgaliyev of Kazakhstan by 0.304 seconds at the Baluan Sholak Arena.

He had earlier posted a Winter Universiade record of 40.589 in the quarter-finals, bettering the mark set by compatriot Lim Hyo Jun in the heats by 0.129 seconds.

Lim’s heat time of 40.718 was 0.339 seconds quicker than the record set by another South Korean, Seo Yira, en-route to victory at the 2015 Winter Universiade.

Third place in the men’s A final went the way of Kazakhstan’s Denis Nikisha, who was a considerable 16.994 seconds back after being involved in a crash for which China’s Chen Guang received a costly penalty.

Lim was also involved in the crash and ended up finishing fourth, 17.250 seconds back.

In the women’s 500m A final, China’s Zang Yize came out on top with a time of 44.015.

Compatriot Xu Aili was 0.109 seconds behind in the runners-up spot, while South Korea’s Kim A Lang - the silver medallist in yesterday’s women’s 1,500m event and the Olympic 3,000m relay gold medallist - was 0.176 seconds off the pace in third.

Japan’s Moemi Kikuchi, the women’s 1,500m bronze medallist, came home last of the four competitors in the A final.

South Korea’s Son Ha Kyung, the women’s 1,500m gold medallist, failed to record a time in her quarter-final and therefore failed to progress any further.

Short track speed skating action is due to conclude tomorrow when medals will be awarded in the men’s and women’s 1,000m events, as well as the men’s 5,000m relay and women’s 3,000m relay.
