the Japanese individuals who killed Chinese are all dead or dying. in the 80s they were already 70 years old. meanwhile Vietnam vets are the typical sex tourist age and they, the individuals, can go back to Vietnam.
Vietnam is more like Philippines or Thailand. they don't have two things that Chinese recognize as important: the sense of fairness and the thirst for scientific knowledge. that is why Vietnam has less scientific publications than Nigeria and is about the level of Kenya despite similar or larger population and higher per capita gdp.
So because VN has low scientific output it has the same IQ level as Africans. And in regards to comparing Vietnam to Thailand & Philippines.
According to these results, we could identify some archetypes of knowledge production in ASEAN countries. While Vietnam has a strong publication record in mathematics and physics [5], Singapore has considerable strength in engineering and biotechnology, Thailand has good track record in food technology, pharmacology and pharmacy, Malaysia in crystallography and engineering, Indonesia in ecology and environmental science, and the Philippines in agriculture and plant sciences.
The 10 ASEAN countries clustered into 4 groups based on the quantity and quality of publication. Singapore being the country with the highest output, followed by Thailand and Malaysia as the second bloc; Vietnam, Indonesia, and the Philippines as one bloc with medium number of publication record; and finally Cambodia, Laos, Myanmar and Brunei as one bloc with the lowest scientific output. However, it is noted that Vietnam is rapidly transiting into the second bloc, with a considerable growth in recent years. Further analysis of research areas revealed some further clusters, with economically advanced countries had better research output in engineering and high technology and biotechnology (Singapore, Thailand, and Malaysia), while less economically developed countries (Vietnam, Cambodia, Laos, Indonesia, and the Philippines) had good research record in “low tech” fields such as public health, and in the case of Vietnam, theoretical physics and mathematics.
Due to poor infrastructure in scientific research, most research projects in Vietnam focused on theoretical areas such as pure mathematics and theoretical physics. While Vietnam had been at war with various powers for almost 100 years, other countries in the region had enjoyed a long period of economic stability. Indeed, the scientific research in Vietnam has really taken off since 1990, when the policy of “renovation” was introduced after a long period of political isolation and economic crisis. It’s thus perhaps not surprising to see that the scientific output from Vietnam has been modest during the first ten years (1991 to 2000), but then rapidly increased during the next decade.
CHEER » Scientific Output and Its Relationship to Knowledge Economy: An Analysis of ASEAN Countries
As you can see VN scientific output is focused mainly on pure math and theoretical physics which is a more hardcore subject. The issue is subject practicality, infrastructure, investment in R&D & Human Capital and government support. If all necessary requirements are met VN will surpass all SEA nations and be at the top of EA nations.
