Russia is joining with China in opposing any US plans to establish a missile system in South Korea.

Russia's opposition to any deployment of the THAAD system is being voiced following a meeting between Chinese Foreign Minister Wang Yi and Russian Foreign Minister Sergey Lavrov.

"Countries shouldn't be using Pyongyang's acts as pretext to increase their military presence on the Korean Peninsula. We believe the possible deployment of the THAAD anti-missile system won't resolve this problem. We hope the six-party talks can be resumed as early as possible, as we have built-up experience in resolving the nuclear issue through negotiations in the past."

Meeting with Lavrov on the sidelines of the now-concluded Conference on Interaction and Confidence Building Measures in Beijing, Wang Yi says the THAAD system represents a potential threat.

"Both sides are gravely concerned about the possible deployment of the THAAD, or Terminal High-Altitude Area Defence system in South Korea by the US, because it goes beyond the actual defence demands of relevant countries. The deployment of the system will directly harm the strategic interests of China and Russia."

The US and South Korean government's have been discussing the potential deployment of the anti-missile system around Seoul and locations in-range of North Korean short-range missiles.

However, the THAAD system has the potential to fire missiles which could hit targets in China and Russia's far-east.
