Well, you're an idiot. Because there are factors like the language in which it was first published, social network, lack of international collaboration and the size of the country's scientific community that can impact the average number of citation per paper, because the best papers can get up to 40,000 citations, a difference of 10 is quite meaningless. In fact, China was 4th in the number of papers that were in the top 1% most cited in 2011.
Other factors such as the importance of seniority, lack of funds for fundamental research and lack of autonomy also negatively impact Asian science.
"An analysis of ISI Web of Knowledge data found that China had increased its share of the 1% of most highly cited science articles from 1.85% in 2001 to 11.3% in 2011."
However, in the U.S. and other Western countries, Asian scientists are overwhelmingly overrepresented in the top over-achieving scientists.
"Indicative of the future, the foreign-born made up over half of doctorate scientists and engineers under the age of 45 in 2000 and 57 percent of post-doctorate workers. Nearly 60 percent of the growth in the number of PhD scientists and engineers in the country in the 1990s came from the foreign-born."
"Scientists and engineers making exceptional contributions to the physical sciences. Regardless of benchmark date or indicator, we find the foreign-born to be disproportionately represented among those making exceptional contributions in the physical sciences (Table 6). For example, more than half (55.6%) of the outstanding authors in the physical sciences are foreign-born compared to just 20.4% of physical scientists in the scientific labor force as of 1980 (Table 1). We also find that the foreign-educated are disproportionately represented for a number of the indicators = among the most-cited and outstanding authors, as well as first authors of hot papers."
