Gini coefficients and growth effect

comments on Cao Xin "China: The question of income distribution", 28/08/2011, http://www.eastasiaforum.org/2011/08/27/the-question-of-income-distribution/
I need to state that I am not an expert on income distribution both on time series and on cross countries. I was wondering, however, whether economic/income growth should be taken into account to judge income distribution in terms of Gini coefficients.
When two economies are having very different growths, the same level or change in their Gini coefficients may have different implications for the disadvantaged in their respective nations/peoples.
This could be a very interesting empirical research topic to see if growth has an impact or not.
