Also worth noting is that China accounts for the majority of the world's capital punishments. The government has been decreasing its number of death sentences, converting from firing squad to lethal injections, and banning the sale of body parts of the executed. But death penalty is still very commonly used, often with quick summary trials.
The Chinese government argues that it is improving human rights, by making its people materially better off. Sorry, but that argument was used by two of your neighbors in the past - South Korea and Taiwan - and in both, the argument was debunked. Only with political reforms did real democracy blossom - and even today, human rights abuses remain, particularly in South Korea.
And speaking of Taiwan's democracy...

Things have changed dramatically since then. Today's Taiwan is ruled by a Taiwan native, President Chen Shui-Bian of Democratic Progressive Party, who has been re-examining Chiang's legacy. While Chiang brought about Taiwan's impressive economic growth, his human rights record left a lot to be desired (especially from the natives' standpoint), and Chiang-related landmarks are either being retired or re-themed. Taipei's international airport is no longer named after Chiang, and now the Chiang memorial itself commemorates Chiang's victims as much as Chiang himself.

I will also note that Chiang was a major supporter of Reverend Sun Myung Moon and his Unification Church, therefore making him partly responsible for the reactionary swing of the US politics over the past three decades.
