Following North Korea’s weekend announcement of a successful ballistic missile test, Russia’s foreign ministry responded Monday and stated it was “concerned” by the latest revelation of Kim Jong-Un’s regime but also stressed for every nation involved to “remain calm,” Reuters reported.

North Korea said it had fired off a new medium-to-long-range ballistic missile Sunday despite resolutions by the United Nation’s prohibiting such tests and the totalitarian regime’s continued advancement of weapons and nuclear materials.

The Korean Central News Agency, the nation’s main information arm, said Kim had directed the test of the surface-to-surface Pukguksong-2, or Polaris-2. The United States and South Korean authorities confirmed the test, The New York Times reported.

The missile reached an altitude of 340 miles and flew roughly the same distance towards Japan before splashing down on the Korean peninsula’s east coast, Reuters reported.

“He expressed great satisfaction over the possession of another powerful nuclear attack means, which adds to the tremendous might of the country,” the KCNA said in reference to Kim according to The Times.

Employing new technology that it had never used before, the new test was thought to be the latest step for North Korea to attack the U.S. with an intercontinental ballistic missile.

“Now our rocket industry has radically turned into high-thrust solid fuel-powered engine from liquid-fuel rocket engine and rapidly developed into a development- and creation-oriented industry, not just copying samples,” Kim was quoted as saying.

Russia’s concern, as well as of that of the U.S., China, South Korea and Japan, has reportedly led to requests for a meeting of the UN Security Council Monday, a U.S. official at the UN told Reuters.

Russia’s foreign ministry also went so far as to say the test was in “defiant disregard” of the UN resolutions, according to CNN.

Russia’s declaration against the test flew in the face of how Kim’s regime evidently feels towards President Vladimir Putin’s. Earlier this month, KCNA revealed that Kim had placed Russia ahead of China for the third straight year on a list of countries’ leaders to receive a greeting card from Kim.
