The US and South Korea have agreed
to deploy a controversial missile defence system, in the wake of
intensifying threats from North Korea.
China, which has consistently opposed the plan, lodged a protest with the US and South Korean envoys. China's foreign ministry said that the THAAD system will harm peace and stability in the region, despite its ability to detect and shoot down North Korean missiles.
"China expresses strong dissatisfaction and resolute objection to this", it said in a statement on its website.
