Russia and North Korea have a lopsided deal, with Moscow reaping far greater support for its war in Ukraine than the benefits received by Pyongyang, according to a study. Published by German think tank Friedrich Naumann Foundation on Thursday, Unequal Partnership reports that North Korea has delivered up to $9.8bn worth of weapons, as well as fighters, to Russia since 2023. Pyongyang's gains may amount to as little as an estimated $457m to $1.19bn.
