China, Koreas are big winners in London

China proved they've arrived as a genuine Olympic super-power, and both Koreas impressed -- but Japan were top of the flops among Asian countries at the London Games.

China's Sun Yang poses on the podium with the gold medal after winning the men's 1500m freestyle final at the London Olympics on August 4.

China may not have repeated their feats of Beijing 2008, when they topped the medals table for the first time, but with 38 golds their presence in the top two, behind the United States, was never in doubt.

South Korea were the only other Asian team in the top 10. North Korea, finishing 20th, had their best Games in 20 years, Hong Kong celebrated cycling silver and Singapore won their first individual medal in 52 years.

India couldn't follow Beijing by claiming their second individual gold, but they finished with two silver medals and four bronze -- their highest individual total.
