China is suspending military exchanges with the United States over its planned arms sale to neighbouring Taiwan.
The state-run Xinhua News Agency said the suspension of the scheduled visits by military personnel is because of the "bad impact" of the 6.4 billion dollar (£4bn) weapons deal on the two countries' military relations.
China has already warned the US the planned arms sale would harm overall relations.
Details of the arms sale were posted yesterday on a Pentagon website.
Taiwan is the most sensitive matter in US-China relations. China claims the self-governing island as its own after the two sides split after a civil war.
