Primitive?
China produces atleast 10 times more Engineering and technology papers than India does, so technically its H-index should be atleast 10 times more than India's. But the reality is that Chinese H-index is just 189 compared to India's 137
China produced twice as many Engineering paper as America does, so one would expect Chinese H-index to be higher than America's if not double. But the reality is that Chinese H-index is about 1/4th the H-index of America.
No matter how you spin it, this doesn't look good, and says a lot about the majority of the research work that the Chinese are doing.
Heck China's cite per document is even lower than that of India
Basically Chines research is mass produced junk which no one even bothers to cite!
