I would say my observations are a little different. All of the OEM gas turbine manufacturers have significant Chinese content. Things have changed drastically there in the last 10 years. For the most part, materials, processes, and quality are on par with anyone else in the world, but you have to commit considerable resources to get it. Well defined specs are necessary. And companies like GE assign their engineers to stay there and work the technical problems. Like anywhere, there are good companies and bad ones, and definetly more risk of IP and trade secret loss. The suppliers I manage there are very impressive to say the least. BTW you can buy stuff from India for about 1/2 the price of China. But that is another story.....
