China has announced a series of moves against the US in retaliation for a proposed weapons sale to Taiwan worth $6.4bn (£4bn).

Beijing said it would suspend military exchanges with the US, review co-operation on major issues and impose sanctions on companies selling arms.

Ties are already strained by rows over trade and internet censorship.

Taiwan's president welcomed the sale, saying it would make his country "more confident and secure".

Beijing has hundreds of missiles pointed at the island and has threatened to use force to bring it under its control if Taiwan moved towards formal independence.

Taiwan and China have been ruled by separate governments since the end of a civil war in 1949.
