The US has been warning North Korea for weeks against supplying Russia with weapons for its war in Ukraine.
But as Russian and North Korean leaders are keen to improve relations between the two countries, Washington can do little to stop cooperation between Moscow and Pyongyang, international news analysts say.
North Korean leader Kim Jong-un is on a visit to Russia these days, and he has spent hours with Putin at the Vostochny Cosmodrome, a space station in the Far East, according to Al Jazeera news service.
In a special statement, North Korean leader Kim Jong Un pledged to support Russian President Vladimir Putin in fighting “hegemonic forces” that threaten Moscow’s security and interests. But the leaders of the two countries did not make any statement about the controversial arms deals.
Russia has been supporting North Korea for some time in the resolutions brought by the United Nations against North Korea, and is currently building very good diplomatic relations.
