South Korea and the U.S. have warned North Korea and Russia that they will, without fail, face consequences if they engage in military cooperation. 

First Vice Foreign Minister Chang Ho-jin told reporters following the fourth meeting of the Extended Deterrence Strategy and Consultation Group (EDSCG) in Seoul on Friday that Pyongyang-Moscow military cooperation is a serious violation of UN Security Council(UNSC) resolutions. 

Chang said Seoul and Washington shared the view that Russia should act in a responsible manner as one of the depository states of the Nuclear Non-Proliferation Treaty and as a permanent member of the UNSC. 

The vice minister said the two sides agreed to actively share information while stressing that the South Korea-U.S. alliance, which is marking its 70th anniversary this year, has never been stronger. 

Chang said the extensive discussions held at the EDSCG meeting will further solidify the alliance.
