North Korea has placed surface-to-surface missiles on launch pads in the Yellow Sea, Yonhap news agency reported Nov. 28, as the United States and South Korea began military exercises and China said it would try to ensure peace.
South Korean President Lee Myung-bak told a visiting Chinese delegation that Beijing, North Korea's only major ally which is traditionally reluctant to criticise the reclusive regime, should do more to help.
China, which agreed with South Korea that the situation was "worrisome", would try to stop it deteriorating, the delegation responded, the presidential Blue House and Chinese media said.
Yonhap also said North Korea had moved surface-to-air missiles to frontline areas, days after it shelled a tiny South Korean island killing four people. The North's official KCNA news agency warned of retaliatory action if its territory is violated.
South Korea's Defence Ministry told journalists to leave the island, Yeonpyeong, because the situation was "bad". Many residents evacuated earlier said they did not want to return.
"We will deliver a brutal military blow on any provocation which violates our territorial waters," KCNA said.
