Russia says it's developing 'sensitive' tie with North Korea

Russia is expanding relations with North Korea in various areas including "sensitive" ones, said Dmitry Peskov, the spokesperson for the Kremlin. Peskov's statement comes after North Korea's foreign minister expressed appreciation for the close relationship between the two countries. The foreign minister then held rare discussions with Russian President Vladimir Putin at the Kremlin. Notably, North Korean leader Kim Jong Un has extended an invitation to President Putin to visit his secretive and nuclear-armed nation.
