Beijing, China (Reuters): China 's Foreign Ministry said on Tuesday it was decisively opposed to the deployment of the Terminal High Altitude Area Defense (THAAD) anti-missile system, after the U.S. military said its first elements had arrived in South Korea.

Ministry spokesman Geng Shuang made the comments at a routine news briefing.

China has repeatedly expressed its opposition to the deployment , saying its powerful radar could affect China 's own security and that it will do nothing to ease tensions on the Korean Peninsula.
