Top seed Lee, the Hong Kong national champion ranked 43 in the world, raced to an 11-5, 11-5, 14-12 victory over Canadian Fred Reid in just 22 minutes.

Lau, the fourth seed and the Hong Kong No2, survived two tie-break games against determined opponent Harinder Pal Sandhu before ultimately prevailing 11-9, 13-11, 13-11 over the Indian in 50 minutes to earn his anticipated place in the last eight.

But there was unexpected Indian success when Mahesh Mangaonkar became the only qualifier to survive the first round after beating higher-ranked Frenchman Lucas Serme 11-5, 11-4, 11-9.

The 17-year-old from Mumbai's reward is a quarter-final clash with home favourite Max Lee.
