i highly doubt chinese gangs in chinatown extort more than lcn as a whole that's just speculation i also bet there are several gangs in the bigger chinatowns not just one and they are not all related-eachother
Saying that they dont extort more than the lcn is just speculation on your part as well.
China town has many tongs that have been around since the 18th century and they often use the street gangs chinese, vietnamese, koreans or otherwise to collect debts, protection money, deal drugs. However these gangs often commit crimes for themselves as well.
