THAAD's deployment opposed

China, Russia say strategic balance to be upset by US-ROK move on missile defense system

China and Russia expressed strong opposition on Friday to the decision by the United States and the Republic of Korea to deploy an advanced missile defense system in the ROK, saying the system will destabilize the balance of security in the region.

Washington and Seoul said in a joint announcement that the Terminal High Altitude Area Defense system will be deployed to tackle the Democratic People's Republic of Korea's nuclear and missile threats.
