BEIJING, Dec. 20 -- China opposes any activities that will undermine the peace and stability of the Korean Peninsula, Foreign Ministry spokeswoman Hua Chunying said Friday.

Hua made the comment in response to a question about a fresh threat by the Democratic People's Republic of Korea to attack the Republic of Korea (ROK).

According to ROK sources, the DPRK's National Defense Commission on Thursday warned of retaliation against the ROK "without any notice," accusing the latter of insulting its "highest dignity."

On Tuesday, some people in the ROK burned effigies of the DPRK leader in protest against the DPRK.

Hua said China has noticed reports about the issue.

"We hope that all relevant parties remain calm and refrain from taking any action or making any comment that may lead to the rise of tensions on the peninsula," she said.

"Maintaining peace and stability of the peninsula is in the interests of all parties and also constitutes their common responsibility," the spokeswoman said.
