China has showcased its long-awaited J-20 stealth fighter in public for the first time.

Two of the radar-evading jets did a 60-second flypast at the Zhuhai air show in Guangdong province - the country's biggest meeting of plane makers and buyers.

Previously the jets had only been seen by bloggers.

The fighters are being seen as symbol of Beijing's desire to modernise and upgrade its military capabilities.

President Xi Jinping wants to toughen China's armed forces as it takes a more assertive stance in the region, especially in the South China and East China seas.

The J-20 has been developed and made by the Chengdu Aircraft Industries Group, a subsidiary of Aviation Industry Corporation of China.

Some have likened the new fighter to Lockheed Martin's F-22 Raptor jet, with industry analyst Bradley Perret of Aviation Week saying the jet was "clearly a big step forward in Chinese combat capability,"
