They PLAN to produce an engine of there own, an electric one at that which, IF successful, will have great advantages over the conventional engines that we see today. For now, they are not using there own engine and yes they will be sanction prone. All this however do not really matter, our issues were not related to the engine and due to some other issues the chapter is closed for now. All we may pursue in future will be some sub systems at best, that too is for future and nothing is on cards right now.
Theoretically speaking, that possess the same problems that a German engine would, right? or any other western engine would.
