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.

Rose Gottemoeller, undersecretary of state for arms control and international security, stressed that the United States and South Korea had just begun discussions, and no decision had been made to deploy the Terminal High Altitude Area Defense (THAAD) system.

Gottemoeller also emphasized that the system is defensive and aimed at North Korea, not China.
