South Korea said on Friday it has made a final decision together with the United States to deploy an advanced missile defense system with the U.S. military stationed in South Korea to counter North Korea's missile threat.

Chinese President Xi Jinping on Wednesday urged South Korea to pay attention to China's concerns about the deployment of the U.S. THAAD missile defense system to the country and "cautiously" address the plan.

China and Russia urged the United States on Friday not to install a new anti-missile system in South Korea, after Washington said it was in talks with Seoul in the wake of nuclear arms and missile tests by North Korea.

The high-altitude system would achieve none of its stated goals if deployed, but would shake the fragile trust of Beijing and Moscow toward Washington. The US should learn some lessons from the Cuban missile crisis and NATO’s eastward expansion, understand and respect other countries’ security concerns, and take some concrete measures to ease instead of aggravate the tension in the Korean Peninsula.

The United States hopes to talk with China and address its concerns about the possible deployment of the THAAD missile defense system that Washington is discussing with Seoul, a senior State Department official said Tuesday.

Amidst Chinese and U.S. opposition, North Korea has amplified its pressure on South Korea and allies through its weapons development. However, China has opposed U.S. deployment of a Terminal High-Altitude Area Defense (THAAD) in South Korea, which could halt progress.
