This is why I don't worry too much about China (amongst many other reasons). They have no blue water navy, and the only people willing to sell one to them at this time are the Russians, who are making death traps for nuclear submarines these days:
First there was the Kursk, now this. Any Chinese sailors on PWI who are waiting to get on the next Russian-built Akula class?
Sure, the Chinese can build their own nuke subs, but it takes time. A lot of time and a lot more money. For now, they'll just have to stick to their 5 knot diesel boats unless they want to end up in Davey Jones' locker.
