1: US psychometricians are the one's testing Chinese people, both in and out of China. The mean IQ is around 106, as assessed by Americans and other international scientists.
2: Indeed, these same psychometricians are the one's that have tested Indians. The mean IQ of India is around 82, which is lower than that of African-Americans.

The fact that the highest-IQ population of Indians has a mean IQ of 110 is quite embarrassing, not impressive. Most Indian immigrants are selected for their educational attainment and/or their income (which is a reflection of very high IQ). For China, the selection process has only been recently in place, due to the fact that many Chinese immigrants had come to the US before the modern era.
