China's air force and navy have announced drills in the South China Sea to help develop preparedness for war, military leaders said, after the British defence secretary indicated the UK would sail a warship through the disputed region. 

The Chinese military's latest fighters and bombers were involved in the exercises over the disputed region, as China continues to flex its muscles on the world stage.

The drills come after Xi Jinping, the Chinese president, gave a nationalist speech last week when he warned of Beijing's willingness to fight a "bloody battle" against its enemies.

They also come after Gavin Williamson, British Defence Secretary, said last month that the HMS Sutherland, an anti-submarine frigate, would sail through the South China Sea to assert freedom of navigation rights.
