The Asian League doesn’t have trades. Players become free agents, are released or loaned from/to other teams. Korean born players, however, must do compulsory military service of at least 24 months. As a result, they are selected to play for Sangmu, the Korean military team, formerly in the Asia League from 2013/14-2015/16 seasons. This team is now part of the Korea Ice Hockey League. After completing their military duty players can return to their original team or sign with another.
As of the 2018/19 season, each team is permitted to sign a maximum of 2 import players. Russian players, however, will no longer be counted as imports and can be signed freely
