Kim Gi-jung and Shin Seung-chan got the hosts off to a perfect start by defeating Zhang Wen and Ou Dongni in the men's doubles encounter before Son Wan-ho required just 31 minutes to dispatch Gao Huan in the men's singles.

Beijing 2008 mixed doubles champion Lee Yong-dae then teamed up with Ko Sung-hyun to complete the job in style, beating Zhang Wen and Wang Yilyu 2-0 in the second doubles contest.

This meant that neither the women's singles nor the mixed doubles was required and victory had been completed in just 90 minutes.

It marked a successful defence of the gold medal for the South Koreans after they also won mixed team gold at the 2013 Summer Universiade in Kazan.

At virtually every venue there was South Korean medal success to celebrate today.

Four more home golds were won in archery on day of finals with the Olympic recurve bow, as Lee Seungyun and Ki Bobae claimed respective male and female individual honours.

There was also men's team success in judo, three poomsae gold medals in taekwondo and a victory for 10 metre air pistol shooter Han Jiyoung.

That puts South Korea comfortably clear at the top of the medals table with an impressive 28 golds in a 59 medal haul after seven of 13 days of action.

China sit in a distant second with 17 golds, with Japan a further one behind in third.

Meanwhile, today marked the first day of athletics finals as Intergeet Singh of India claimed the men's shot put title while Russia's Alla Kuliatina crossed the line first in the women's 10,000 metres with a personal best time of 32min 52.27sec.
