Ice hockey's governing body has invited European national federations, leagues and clubs to talks about reviving a continental competition, and their relations with the NHL.
The International Ice Hockey Federation says stakeholders will meet at a June 12-14 forum in Barcelona, Spain.
IIHF president Rene Fasel says "the focus will be on finding a format for a competitively and commercially viable top European club competition."
It would follow the Champions Hockey League which folded with financial problems after its debut 2008-09 season.
Fasel says "key points" will include co-operation with the NHL, the NHL players' union and the Canadian (Junior) Hockey League.
