China is to promote its Y-20 heavy transport and fifth-generation J-31 fighter aircraft at the 11th China International Aviation and Aerospace Exhibition, which is set to open on 1 November in the southern port city of Zhuhai, Guangdong Province, according to Xinhua news agency.

The state-owned Aviation Industry Corporation of China (AVIC) will prominently display the two aircraft, which are built by AVIC subsidiaries, at the six-day aerospace trade show, said the media outlet.

The first two Y-20 aircraft were delivered in June to the People's Liberation Army Air Force (PLAAF) after nearly a decade of design, development and test flights. Built by the Xian Aircraft Corporation, the Y-20 reportedly has a maximum take-off weight of 200 tonnes and is designed to carry cargo and people over long distances and in difficult weather conditions.

The transport aircraft made its maiden flight in January 2013 and debuted in November 2014 at the 10th China International Aviation and Aerospace Exhibition (also known as the Zhuhai Airshow).

The J-31 fighter, which is manufactured by the Shenyang Aircraft Corporation, is the second stealth-enhanced fighter that China has indigenously developed after the Chengdu J-20. Its maiden test flight was reportedly completed in October 2012.
