NATO chief Jens Stoltenberg is to meet with Hungarian Prime Minister Viktor Orban in Budapest on Wednesday amid tensions between the central European country and the defense alliance over Russia's invasion of Ukraine.

As Moscow's closest EU ally despite its invasion of Ukraine, Orban is increasingly stoking fears of a war between the West and Russia, which he blames on Brussels and NATO.

The nationalist premier recently also suggested he would like to "redefine" the position of Hungary in the alliance to prevent any participation in operations "outside NATO territory."
