The decision was made in reaction to Russia's aggression in Ukraine.
"The decision to leave the KHL has been made, expressing a clear position of the club's management. In such a military and humanitarian crisis, we do not see any opportunity for cooperation with the KHL," the chairman of the club council Juris Savickis was quoted as saying in a very brief statement published on the club website.
The general sponsor of Riga Dinamo is Russian state-controlled fuel giant Gazprom.
As previously reported by LSM, the club had already announced an early end to the current season.
