SARAJEVO, Bosnia-Herzegovina — Bosnian officials on Friday denounced a Russian warning that it will take action if the country takes steps toward NATO membership.

The Russian embassy in Sarajevo had said a day earlier that “in case of practical rapprochement” of Bosnia and NATO, “our country will have to react to this hostile act.”

It was not clear from the statement which what action Russia might take against Bosnia, which has long proclaimed membership in the Western military alliance and in the European Union a strategic goal.

Zeljko Komsic, the Croat member in Bosnia’s tripartite presidency, said that Moscow’s statement represents “a veiled threat” not only against Bosnia, but also against its Western allies, including the United States.

“It’s clearly a geopolitical game which Russia is playing to stop the expansion of NATO in Europe,” Komsic said.

The main Bosniak Party of Democratic Action said that the Russian statement represents “another inappropriate meddling” by Moscow in Bosnia’s internal affairs.

Bosnia is part of NATO’s Membership Action Plan, an advisory and assistance program designed for countries wishing to join the alliance.

Bosnia, Kosovo and Serbia, a Russian ally, remain the only Western Balkan nations that are not NATO members. Montenegro joined the alliance in 2017 while North Macedonia became a member last year.

Bosnian Serbs, who control about half of Bosnia after a U.S.-sponsored peace deal that ended a bloody war in the 1990s, are closely allied with Russia and remain vehemently opposed to NATO membership.
