Khan, gold medallist in the under-58 kilograms category at last year's South Asian Games in Nepal, told Pakistani newspaper The News the Games being pushed back to 2021 will be beneficial to his training.

"I want to qualify for the Tokyo Olympics," he said.

"I have resumed training at Balochistan International Taekwondo Academy which is very close to my home.

"Because of the delay in Olympics I will get a chance now to regain my rhythm ahead of the Asian qualifiers.

"I believe in myself and will try my level best."

World Taekwondo postponed its Asian qualifier, which had been due to take place in Wuxi from April 10 to 11, because of the coronavirus pandemic.

The event has been moved to Jordanian capital Amman and is set to be held in June.

Khan said his success at the qualifier would depend on "several things".

"How I regain my fitness, rhythm and confidence as it is always not so easy after injury but believe me I am determined and aim to do something stunning," he said.

"My main aim is to make it to the coming Olympics."

Tokyo 2020 was postponed due to the COVID-19 pandemic and has been rescheduled for July 23 to August 8 in 2021.
