Missile defense systems in North Korea

The deployment of ballistic missile defense systems around North Korea by the United States and its allies could be an effective way to change China's strategic thinking about Pyongyang, a U.S. congressional report said.
The Congressional Research Service made the point in a recent report, "North Korea: U.S. Relations, Nuclear Diplomacy, and Internal Situation," saying Beijing would find it not in its national interest if provocative actions by the North lead to increased military deployments in the region.
