Is China capable of developing vector engines now?

Of course, it has developed for decades. The successfully developed Taihang Qinling Kunlun series is a remarkable achievement of China's aero-engine in recent years. In order to catch up with the international advanced level, China has never stopped the research and development of aero-engines such as vector engines, just because it is not as easy to develop this kind of precision military industry as to build cars. No matter Russia, the United States or European countries are developing aviation. The engine has experienced ups and downs, and China is no exception, so at present, China people have not seen any domestic aero-engines with excellent performance, but please believe that in the near future, China's own domestic large aircraft will fly in the blue sky.
