It sounds like the Chinese guys who he got into fight with were willing to drop the charges for $100,000 US. He didn't have the money. No one was seriously injured. He had been coaching football and teaching English in China.

Pretty much why I'll never go to China
much better to live in a country that hands down 4 year sentences for pushing a guy instead, right?

or a country that sentences someone to 18 months in prison for defending themselves against a burglar who broke into their dark house in the middle of the night with their elderly grandmother sleeping in another room?

Korea has a sh*t legal system and lack of civil pressure (Confucian teaching of not upsetting the "natural" order) means it's slow to reform. Still, in Korea, if you're a foreigner and you're embroiled in a legal dispute with a Korean, while you might face some bias, you definitely have a chance, particularly if you have evidence.
Furthermore, the example you've given, in Korea's case, illustrates a poorly thought out, ambiguous and vague legal system, it does not illustrate bias. China's legal system, from a position of a foreigner is PURELY bias, it doesn't matter how much evidence you have or how strong your case is, a Chinese court will NEVER take the side of a foreigner over a Chinese national, under any circumstances.
Apples and oranges.
