BEIJING - China will insist on peace and denuclearization on the Korean Peninsula and will object to any nation causing trouble in the region, a high-ranking Chinese diplomat said on Monday when talking about China's diplomatic policies in the next five years.

"The peninsula must be stable, and it must be denuclearized," said the official in charge of policy planning at the Foreign Ministry who declined to be named.

He made the remarks at a background briefing on the new five-year plan for China's diplomacy.
