From Wiki...
“However, recently, because of China’s recent conflicts with Turkic Uyghur separatists, relations have at times been strained.”
I’m sure Honda or Porsche would be glad to step in and fill the gap.
Well....
Thielert made an entry into Gen-Av with a Diesel(s) and had problems and I believe were bought out. Both Honda and Porsche have dabbled with Gen-Av. Honda showed off a letter of Memorandum Engine with Teledyne Continental a number of years back @ Oshkosh and Porsche designed and certified for production a version of the 911 engine with not a lot of success and got out of the business. If my memory is correct the Thiehert entry was esentially a Mercede's auto engine with a limit on TBO, i.e. new engine @ overhall. What is going on here is China gets a Diesel Gen-Av type engine which is required for UAV's via NATO Heavy Fuel Requirements.
What is disturbing is China also bought Teledyne Continental Piston Engines as well a while back. They are buying up everything they can get their hands on, in this arena. Not Good, IMHO...
