China has reiterated its opposition to deployment of the Terminal High Altitude Area Defense - an advanced US missile defense system - in the Republic of Korea, as a special envoy visited Seoul.

Wu Dawei, China's special representative on Korean Peninsula affairs, started a visit to the ROK on Sunday and met with Hwang Joon-kook, ROK special representative for Korean Peninsula peace and security affairs, who is also Seoul's top envoy to the Six-Party Talks.

Wu talked with Hwang before meeting separately with ROK Deputy National Security Advisor Cho Tae-yong and ROK First Vice-Foreign Minister Lim Sung-nam on Monday, China's Foreign Ministry said.
