China is rapidly becoming a major manufacturer, and developer, of modern weapons. Russia, which involuntarily supplied much of the technology Chine needed, discovered this recently when they saw what Chinese engineers had done to the AL-31 engine that powers the Russian Su-27/30 and Chinese J-11 and J-10. As delivered from Russia, the AL-31 is good for 900 hours of operation. Chinese engineers figured out how to tweak the design of the engine so that it lasted for 1,500 hours. This feat is part of a growing trend. At first, decades ago, China simply figured out how to build Russian weapons they had bought. But in the last decade, they have increasingly improved on those designs.
Most of this technology was just stolen from Russia, so now Russia is no longer selling China much of anything.
China knows how to make the rope, now. This would be funny if the repercussions were limited to Russia alone.
