Chinese Foreign Minister Yang Jiechi called Sunday for "an appropriate and balanced" U.N. Security Council resolution over North Korea's nuclear test, apparently signaling that China won't accept tougher sanctions against Pyongyang, a Foreign Ministry official said.

During talks with Yang in Tokyo, Foreign Minister Hirofumi Nakasone emphasized the need to "swiftly" adopt a "strong" resolution and pointed out that China's role is important in preventing North Korea from taking provocative actions.

Yang, however, told Nakasone that peace and stability on the Korean Peninsula are also important and that China wants "an appropriate and balanced" United Nations resolution.
