TOKYO: China has wrapped a record-setting first day of rowing finals by smashing the world record in women's quadruple sculls and winning gold.
The Chinese boat finished in 6 minutes, 0.13 seconds and shaved nearly two seconds off the previous mark set by the Netherlands in 2014.
The race was never close.
Poland won silver more than 6 seconds behind the Chinese.
Australia won bronze for that country's fourth medal of the day.
Windy conditions produced a strong tailwind for the rowers at Tokyo's Sea Forest Waterway, and new world or Olympic records were set in each of Wednesday's six medal races.
The Netherlands have set a new world record in men's quadruple sculls with a sprint over the final 500 meters to win the gold medal.
Their time of 5 minutes, 32.03 seconds beat the previous mark of 5:32.26 set by Ukraine at the 2014 world championships.
The Dutch boat was fourth after the first 500 meters but had closed to second by the next marker.
A late push overtook Great Britain for the lead.
Great Britain then held off a late charge by Australia to win silver.
Australia's bronze was the country's third medal of the day after winning gold in men's and women's four.
