BEIJING, Feb. 28 (Xinhua) -- The Chinese mainland resolutely opposes any form of official or military contact between the United States and Taiwan, a spokesman said Wednesday.

The Chinese mainland firmly objects to U.S. arms sales to Taiwan under any pretext, said An Fengshan, spokesman for the State Council Taiwan Affairs Office, at a press conference.

The one-China principle is the political foundation of China-U.S. relationship and the fundamental guideline for handling issues regarding Taiwan for the two countries, An said.

Asked about some Taiwan media stirring up trouble following remarks by members of a U.S. think tank, An said some "unscrupulous" people from the island acted actively as other countries' tools, at the cost of peace and stability across the Taiwan Strait and the wellbeing of people on both sides.

An called on both sides across the Strait to work hand in hand to create brilliance.
