BEIJING, April 10 (Xinhua) -- China firmly opposes any forms of official and military ties between the U.S. and Taiwan, a mainland spokesperson said Wednesday.

Ma Xiaoguang, the spokesperson for the Taiwan Affairs Office of the State Council, made the remarks at a press conference in response to media reports that the American Institute in Taiwan (AIT) confirmed active military personnel have been stationed at the AIT since 2005.

The U.S. should honor its commitments, correct its wrongdoing, abide by the one-China principle and the three China-U.S. joint communiques, exercise caution and prudence when handling Taiwan-related issues to avoid serious damage to China-U.S. relations and cross-Strait peace and stability, Ma said.

"We oppose any forms of military exercises and the development of military relations between the U.S. and Taiwan. This position is consistent and clear," said Ma while being asked to comment on media reports that the U.S. plans to deploy air defense missile in Taiwan.
