David Cameron defends China trade mission

British Prime Minister David Cameron has defended his trade mission to China after criticism in the Chinese media.

One state-run newspaper cast doubt on the "sincerity" of Mr Cameron's diplomacy amid ongoing anger about his meeting last year with the Dalai Lama.

And it suggested China did not need better relations with the UK as it was no longer a "big country".

Mr Cameron said the trip had seen £6bn in trade deals and "substantial discussions" with China's leaders.
