South China Sea: Xi Jinping attends massive naval display

China's leader Xi Jinping has attended a massive naval display in the disputed South China Sea.
Speaking from an undisclosed location, Mr Xi said the need for a strong navy had "never been more pressing".
More than 10,000 naval officers, 76 fighter jets and a flotilla of 48 ships and submarines took part in the drill.
It came ahead of planned live-fire military drills by China in the narrow strait separating it from Taiwan on 18 April.
- The 'globalisation' of China's military power
- China's military shifts signal bigger changes
- Why is the South China Sea contentious?
Footage broadcast on Chinese state TV showed the leader addressing forces aboard a navy destroyer before watching jets take off from the country's sole aircraft carrier.
Chinese media described the display as the largest of its kind.
Beijing has the world's largest military and has sought to expand its naval power in recent years.
But there has been growing tension over parts of the South China Sea involving a number of countries, including China, Vietnam and the Philippines.
As part of its territorial claims, China has been involved in island-building. Meanwhile the US has sent military vessels and aircraft to the region in what it describes as "freedom of navigation operations".
Most recently, a nuclear-powered US aircraft carrier travelled through disputed waters in March.
