Chinese players were able to play for teams in the 2018 Pyeongchang Winter Olympics
The International Ice Hockey Federation (IIHF) has agreed to review the eligibility of Chinese players.
The IIHF is looking at rules that allowed NHL-qualified players to take part in the 2018 Winter Olympics in Pyeongchang.
The application by Chinese professional football clubs to FIFA turned down and Chinese players took part.
The IIHF said it was co-operating with the World Anti-Doping Agency in an effort to resolve the issue.
“We will review with Wada and China the current arrangements in place for the inclusion of Chinese players to be able to take part in the Winter Olympics,” said Andrea Orr, chief executive of the IIHF.
“It is important to protect the integrity of our competitions and the high standards of conduct required of our athletes.”
Rights to Chinese athletes apply to the state sports association, while most national ice hockey teams and clubs are currently affiliated to the Canadian National Hockey League (NHL).
However, under rules issued in 2000 the NHL could control the rights to talent in China.
