Kim and Shoigu “exchanged their constructive opinions on the practical issues arising in further strengthening the strategic and tactical coordination, cooperation and mutual exchange between the armed forces of the two countries and in the fields of their national defence and security,” North Korean state news agency KCNA said on Sunday.

The North Korean leader met Russian President Vladimir Putin on Wednesday and discussed military matters, Ukraine issues, and deepening cooperation.

Mr. Kim also toured Russia’s Pacific Sea Fleet, equipped with strategic nuclear submarines among other military vessels, KCNA said, quoting him as praising the fleet for its contribution to peace in the region.

The trip marks “a fresh heyday of friendship and solidarity and cooperation is being opened up in the history of the development of the relations between the DPRK and Russia,” KCNA said.
