There is a difference from being critical and being "gleeful" and frankly I think the article leans towards the latter. The author only saw the shortcomings of China and none of her strengths. If someone wrote an article on how millions of Indians are living in poverty and corruption is rampant and how maoists and terrorits will contribute to the imminent collapse of the country I think you'd think that the writer is being overtly negative as well.
Yes, if someone wrote how millions of Indians are living in poverty and corruption is rampant and how maoists and terrorists will contribute to the imminent collapse of the country or on Kashmir, I had think negative as well
Unlike the issues you mentioned above, issues about economy are always debatable.
The only conclusions that one can reason out of the article are
1.Low unemployment that will increase inflation, coupled with appreciating currency, is going to affect the growth rate of the Chinese economy.
2.Most of the Chinas growth has been through exports, and devalued currency with lower tax rate have given more incentives to producers to further export, hence China economy is more export oriented than a domestic one
3.Mass migration of people from rural China to urban China have increased wages in turn food prices, hence food inflation
4.Higher inflation, increased unemployment, appreciating currency, rising interest rates could affect future growth rate of Chinese economy
And, IMO, all the above conclusions can be debatable
