Each of the 206 National Olympic Committee (NOC) can enter a maximum of 2 competitors per gender and each of the five continents must be represented in each gender but if no athletes qualify the host nation will also qualify.
A National Olympic Committee (NOC) is a national constituent of the worldwide Olympic movement. As of 2020, there are 206 National Olympic Committees. Each National Olympic Committee (NOC) can enter a maximum of 2 competitors per gender should they both rank in the top 4 in the junior world rankings. Otherwise each NOC will only be allowed a maximum of 1 competitor per gender. Each of the five continents must be represented in each gender thus the highest ranked player from each continent automatically qualifies. Should they qualify no athletes the top ranked athlete from hosts China will also qualify, however this did not happen as China already qualified two athletes in each gender.
