Russian President Vladimir Putin hosted a meeting last week with his Belarusian ally, who suggested that Minsk could join Moscow’s efforts to revive an old alliance with Pyongyang after last week’s summit with North Korean leader Kim Jong Un.

Belarusian President Alexander Lukashenko made the proposal as he met with Putin in the Black Sea resort of Sochi, where the Russian leader said he would brief him about the talks with Kim on Wednesday at the Vostochny spaceport in Russia’s Far East.

The U.S. and its allies believe that Kim will likely supply ammunition to Russia for use in Ukraine in exchange for receiving advanced weapons or technology from Moscow, a deal that would violate the U.N. sanctions against Pyongyang that ban any arms trade with North Korea.
