Agree 100%, and anyone who thinks otherwise is an IDIOT and a Knee Jerk Reactionary. The Chinese are not as closely as innovative as the Russians were, not by a long shot, and the Soviet Union is no more.
And just like the Russians, they build their stuff on the cheap. No self respecting US Submariner would ever set foot in a Rickshaw Rick or Ruskie submarine, they are just plain too dangerous.
