China on Thursday said a contingency plan made by Japan and the United States for a possible military conflict across the Taiwan Strait should follow the one-China principle.

News reports said Japan and the United States would discuss the plan this February with an aim to curb China's rise in East Asia.

Chinese Foreign Ministry spokesman Liu Jianchao said Taiwan is an inalienable part of Chinese territory, and whatever considerations between Japan and the United States should firmly adhere to the one-China policy.

"China-Japan and China-U.S. relations are improving, and we hope relevant parties can do more positive contribution to the development of bilateral ties," Liu said.
