China tests new stealth jets built with stolen F-35 design during Obama visit

China conducted test flights of its new stealth jet prototype, reportedly built with stolen design of F-35 Joint Strike, during US President Barack Obama's visit to Beijing for the Asian economic summit this week.

According to FOX News, demonstration flights by the new J-31 fighter jet- China's second new radar-evading warplane-were a key feature at a major arms show in Zhuhai, located near Macau, on Monday.

Meanwhile, Obama urged China to restrain from cyber theft of trade secrets during meetings with the country's ministers.

China procured the design for its new stealth jet from the F-35 Joint Strike Fighter through cyber attacks against Lockheed Martin.

The technology has been used in China's first stealth jet, the J-20, and in the J-31. Both of the jets' design features and equipment are similar to those of the F-35, the report said.
