During a peacetime economy. Don't forget during war time, your factories are being bombed. You're pre-war numbers don't indicate what your war time numbers will be. China's manufacturing tends to be focused around the easter coast and it's rivers. The USAs is spread throughout the country. The USA is pretty good at setting up factories. My understanding is China is more into single large factories. The USA is a net exporter of oil (that greases the entire machine). China is an oil importer (not good when you country is being sieged during war).
