Earlier this month, citing a report by Japan's Asahi Shimbun newspaper, Phoenix Television said the J-18 had completed a test flight at a field base in the Inner Mongolia Autonomous Region.
The report said the wings of the jet, similar to Russia's Su-33, a carrier-based multi-role fighter, could be folded, and suspected that it would be installed on China's future aircraft carrier.
The report came at the same time as foreign media speculated that China's first aircraft carrier, a modification of the Varyag bought from Ukraine, would take to the oceans in July. The Chinese military has denied such reports.
Ding Zhiyong, a spokesperson at the AVIC, told the Global Times on Monday that the Japanese report of the alleged J-18 was pure speculation and that the corporation had no information to reveal.
Li Daguang, a professor specializing in military strategy at the National Defense University, told the Global Times earlier that even if the rumored carrier were true, the vessel would only be used for training.
