the Nihewan people were purely East Asian 5000 years before the Common Era, and possibly 15000 years BCE
that doesn't mean that modern Chinese are 100% offsprings of a solely Chinese Homo Erectus, or that the modern Chinese has totally different genealogy from 1,3 million years. That is wrong, even inside China, because mathematically is impossible. Chinese and non-Chinese people are alive, have DNA and statistics aready exists.
According to strict IQ tests East Asians perform better. Data are not racism, also it's data about IQ, not other property/quality/attribute like beauty for example. The fact that East Asian IQ is superior is sure, and it has been tested even for the conditions of slightly poor East Asian families in relation to non East Asians. Even if we take culture into account, in some tests that has also been in focus with estranged from Asian culture East Asians; they still have a superior IQ.
China is cruel for not producing enough Chinese and allow some to get other citizenships in order the Earthling IQ gets improved. Data are data, not racism; for example East Asians have penile smallness especially when compared to the Congolese cohort. Ok we shouldn't reveal all the time negative data, because humans have emotions; but we should act and help other countries not to be slow-witted, because slowwits will hinder humanity in general, including China.
China being egotistical doesn't create enough Chinese people to intellectually support humanity. Also we cannot blame small East Asian nations, neither Japan who selects a ceremonial leader because of his genes; and not his talent to trick some authoritarian party in order it supports him. Commies might be totalitarian, but they don't have a genetically selected ceremonial ruler; and the General Secretary of the Communist Party of China might have some "dark art" talents, but are certainly his talents; (or hers, because the Chinese accept women theoretically and legally).
