Before all of this, Saddam Hussein was looking for Western arms, but none was willing to sell, so he went after the Soviets and Chinese. You do not sell sophisticated weaponry without providing training, and I do not mean just how to read and execute the user's manual.d on one hand minus the thumb. We did not sell the F-14 to Iran When I was active duty and on the F-111, the list of air forces that can fly a variable sweep wing aircraft can be counte and left the Iranians on their own. At the time, the F-14 was a complex weapon system that required two human beings to operate.
Further, you train your customers based upon YOUR knowledge and experience of the system. You can scale down, but not scale up, meaning we did not train the Iranians on carrier operations for the F-14 because the Iranian Navy did not have an aircraft carrier, so if somehow Iran can make the F-14 and sell to someone else, the Iranians cannot train the customer on how to use the F-14 from ships, even though the Iranian version of the F-14 might be fully capable of withstanding carrier operations stresses. What this mean is that %99.999 of the time, you already know your customer's technical sophistication and will offer wares that you believe the client can understand and execute AT YOUR LEVEL of experience.
So for these PDF yahoos to insinuate that China did not train the Iraqi Army is absurd. But of course, none of them ever served a day in their countries' armed forces so they cannot talk with any understanding in the first place.
