China has lodged stern representations with the Republic of Korea after it deployed the remaining launchers of an advanced US anti-missile system, a Foreign Ministry spokesman said on Thursday.

"We, again, urge the United States and the ROK to value the security interests and concerns of China and other regional countries, to immediately halt the deployment process and withdraw related equipment," ministry spokesman Geng Shuang said at a daily news conference in Beijing.

Earlier on Thursday, four mobile launchers and other elements, such as a power generator, of the Terminal High Altitude Area Defense missile interception system were transported to Seongju, some 217 km south of Seoul, by US trucks, according to Xinhua News Agency.
