The federation says it has not observed any significant changes in the situation that could allow athletes from the two federations to return to the World Cup circuit.
For this reason, no vote was held on the issue during the congress in Berchtesgaden, Germany.
When the International Olympic Committee (IOC) announced this summer that Russian athletes would be allowed to participate in the 2028 Summer Olympics in Los Angeles, the IBU said the federation "took note" of the IOC's decision, but that biathlon would not follow suit.
On Saturday, Slovenian Tim Farcnik was also elected as the new IBU president after outgoing Swede Olle Dahlin.
