SEOUL, South Korea (AP) — Russian state media say Russian President Vladimir Putin and North Korean leader Kim Jong Un have signed a partnership deal during a summit in Pyongyang. Russian state media said Putin and Kim spoke face-to-face for about two hours in a meeting Wednesday that was originally planned for one hour. Putin’s visit comes amid growing concerns over an arms arrangement in which North Korea provides Russia with badly needed munitions for Moscow’s war in Ukraine in exchange for economic assistance and technology transfers that could enhance the threat posed by Kim’s nuclear weapons and missile program.
