I just like the way the answer was phrased. the answer of "we're not that stupid" gives the subtext that it is stupid for anyone to even consider it.
I agree that there's no reason the PLAN won't have as many submarines overall compared to the USN, considering the PLAN is heavily skewed to SSKs while the USN is a wholly SSN fleet. I think the answer was in the context of PLAN matching USN SSN/SSBN numbers, whcih would be folly and needless.
I also think that once contractors are able to develop a modern design (whenever that is), the PLAN should not hesitate to invest heavily in such vessels, even possibly at the expense of a slight decrease in surface combatant commissioning rate; that said I expect by that time, the PLAN's surface fleet will be almost wholly modernized anyway.
