It means the sport's Race to Tokyo rankings will not change and players can start looking ahead to this year's rearranged Games, which open on July 23, pending national selection.

Thirty-eight players are due to contest both the men's and women's singles in Japan, while there will be 32 pairs in men's, women's and mixed doubles.

In singles, a country is limited to two places within the top 16 of the rankings or one place if this does not apply.

Each continent is guaranteed representation, while there are six invitational places from the Tripartite Commission across the men's and women's tournaments.

Badminton's qualification process for Tokyo 2020 has been severely disrupted by the COVID-19 pandemic.

The last three events of the qualification window - the Indian Open, Malaysian Open and Singapore Open - were all cancelled to deal a blow to players hoping to force themselves into the Olympic reckoning.

The qualification window will officially close on June 15.

"The Olympic qualification process is in effect closed as there are no additional opportunities for players to earn points," said BWF secretary general Thomas Lund.

"However, we still need to receive confirmations from National Olympic Committees and Member Associations, followed by any possible reallocations, and this will take a number of weeks to complete."
