China aims to have more track and field athletes qualified for more events and win more medals from the Tokyo 2020 Olympic Games than that in Rio, China's General Administration of Sports said on Monday.

"Athletics has always been very important, fiercely contested by world's sporting powers. In the 2020 Tokyo Olympic Games, athletics will offer 48 gold medals, accounting for 15 percent of the total," said Tian Xiaojun, a senior official of the Administration, at an athletics conference in Kunming, southwest China's Yunnan Province.

However, China didn't yield fruitful results in the sport from the 2016 Rio Olympics, winning only two gold medals.

"We must face to the fact that we are falling behind and breakthroughs have to be made through hard work," said Tian.

Meanwhile, Tian also put emphasis on the fight against doping.

"We will continue to gear up our anti-doping efforts to ensure all Chinese athletes at the Games are away from such a scandal," said Tian.
