>2. They do not care about foreigners or crimes unless they involve Chinese citizens.

Don't know if they really care that much about Chinese citizens. Probably just the ones in the politburo.

It's worked out remarkably well for Chinese citizens given they don't care at all about them, then

Their GDP per capita still lags significantly behind Taiwan, South Korea, and Japan who all aligned themselves with the west.

Millions also died due to their rulers through the 20th century.

India seems like the much more obvious comparison than those countries

Millions died due to their rulers in the decades before the Communist Party, too.

Chinese citizens are treated fairly similarly. There are plenty of unlawful activities that go unpoliced/unpunished (massage parlors), unless there happens to be a specific crackdown going on (otherwise, the police know what is going on and are probably getting a cut).
