Yeah, sure... Then compared to it's counterparts Chinese would be merely 'pocket-carriers'. The costs of maintaining and providing for a fleet of aircraft carriers is none compared to a simple design and building one coming from the 30 years ago technology it seems. China is on the new wave and it takes considerable amount of money to keep it operating. None of the hardships are met by China yet (like inventing something new that doesn't work well). And it's not an easy task to work it out (because keeping a carrier in some remote African naval base is meaningless as it could be cut off from mainland easily). And money won't be coming the same way in the near future...
For now China doesn't have a single operational vessel of this class. And high tech? They will have to pay for it soon.
So what are talking about? Extrapolations from the start of this century?
He's saying that your claim about China being unable to pay for its carriers (or it's military overall) is false, because going by the high end estimates of its annual defence spending it is close to the international average in terms of % of GDP spent (it is actually even lower), and is far lower than the US defence expenditure as % of its GDP.
And frankly you're making a lot of other assumptions in your original post as well, like the idea that China will only have a couple of carriers for the next 20 years (!) and you seem to describe them as future white elephants with the purpose of political posturing than military capability.
If you want to discuss the future of the Chinese carrier programme then by all means do so, but jutting in right now with such poorly articulated negativity and skepticism just as such a milestone has been achieved in the construction of 001A only makes it seem like you're interested in trying to water down a nice moment of interest for everyone else, rather than any serious discussion.
