Generally speaking, Chinese parents assume strength, not fragility, in their kids. That is why they tend to be more strict with their kids. I also like the last paragraph of Chua's piece. That sounds a fair summary of the key differences in thinking between Western and Chinese parents.
"Western parents try to respect their children's individuality, encouraging them to pursue their true passions, supporting their choices, and providing positive reinforcement and a nurturing environment. By contrast, the Chinese believe that the best way to protect their children is by preparing them for the future, letting them see what they're capable of, and arming them with skills, work habits and inner confidence that no one can ever take away."
