Chinainfo-icon's military will display some of its most advanced weaponry and equipment when the country's largest airshow gets under way this week.

Airshow China opens in the southern city of Zhuhai on Tuesday after a year-long delay as a result of the coronavirus pandemic.

The state-run newspaper Global Times reported there would be "dazzling flight performances" involving the J-20, the air force's's most advanced fighter jet.

Other advanced aircraft including the J-16D electronic warfare aircraft, WZ-7 high-altitude drone and WZ-8 high-altitude, high-speed drone, would also be on static display at the outdoor exhibition area for the first time, the paper said.

The show, highlighting the country's efforts to improve homegrown aerospace technologyinfo-icon, comes amid growing strategic rivalry in the Asiainfo-icon Pacific.

The United Statesinfo-icon, the United Kingdominfo-icon and Australiainfo-icon recently announced a trilateral security pact for the region, including the provision of nuclear-powered submarines to Australia, while the Quad leaders met in person for the first time at the White House on Friday.

The Quad includes the USinfo-icon, Australia, Japaninfo-icon and Indiainfo-icon and is seen as an effort to counter the rise of China, which has become increasingly assertive in the region, particularly in the disputed South China Sea and over Taiwaninfo-icon.

"As China faces increasing threats from the West, it needs to improve its military-industrial, aviation and aerospace capabilities," said Song Zhongping, a military commentator and former PLA instructor on missileinfo-icon technology.

The J-16D has two large electronic warfare pods on its wings, which will be used to disrupt and jam hostile electronic equipment, including radar and communications systems, the Global Times reported. It also has a new avionics system and domestically-made engines.

More than 100 aircraft have registered for display in the air or on the ground as China shows off its military might and its spaceinfo-icon ambitions, including a next-generation crewed rocket and heavy-lift launch vehicle.

The flying displays will featureinfo-icon some products China wants to export, including the AG600, the worldinfo-icon's largest amphibious aircraft, designed for fire-fighting and sea-rescue roles.

The Wing Loong II, an armed drone similar to the American MQ-9 Reaper, has already been sold to customers including the United Arab Emiratesinfo-icon, Saudi Arabiainfo-icon, Egyptinfo-icon and Pakistaninfo-icon as China competes against Western rivals to increase military exports.

A new series of drone products named Feihong, including an unmanned helicopter, loitering missiles and a new generation of stealth drones, will make their debut at the show.

"Beijing is intent on not just pushing locally made military aircraft and aerospace technologies, but also its ability to address almost any military requirement out there," said Kelvin Wong, a Singaporeinfo-icon-based defence technology analyst at Janes.

Taiwan has complained repeatedly of incursions by China's air force. Beijing claims the democratically-governed island as its own.

China has also built artificial islets and established military outposts far into the South China Sea, which is also claimed by Vietnaminfo-icon, the Philippinesinfo-icon, Malaysiainfo-icon, Bruneiinfo-icon and Taiwan.

Its claim to almost the entire sea, based on its controversial nine-dash line, was dismissed by a courtinfo-icon in The Hagueinfo-icon in 2016 after the Philippines took legal action. Beijing has ignored the ruling.
