Phelps sets record for the most golds won by an athlete at a single Games; China secures biggest single-day gold medals haul, taking tally to a record
China celebrated its greatest day in Olympic history as diving diva Guo Jingjing led a remarkable haul of eight gold medals to pile the pressure on the US for sporting supremacy.
The haul swelled China's gold medal tally to 35, eclipsing their previous record of 32 in Athens four years ago. The haul also beat the six golds they won on a single day in Sydney in 2000.
On a day of records, Guo also became the most successful woman diver in Olympic history, then denied media reports she was retiring.
China now has 16 more gold medals than the US and 61 medals in all, four behind America's total of 65.
But deputy sports minister Cui Dalin warned that the hosts could not maintain that frantic pace and the medals would dry up with the Games now in their second week.
