The genetist claims that SE Asia to North East Asia migration may not contradict the anthropologist claim to North East Asia migration to SE Asia.
It appears that the proto people migrated from India, enter SE Asia through Myanmmar, from the inference of genetist. Date is 60,000 BP. From Myammar, the gene spread to SE Asia and E Asia. That is the first wave.
There are later wave of migration from East Asia to SE Asia. The anthropologist state that Malay started migrating from Taiwan around 5000-6000BP. So the next wave starting from Taiwan could have spread Malay throughout Oceania. The Thai start moving to SE Asia 1500BP. Meanwhile Burmese move to present day Myanmar.
Below, some Chinese admit they came from SE Asia
Migration of Malay.
Migration of Thai
History of Thailand - Wikipedia, the free encyclopedia
Wiki states
Prior to the southwards migration of the Thai people from Yunnan in the 10th century, the Indochina peninsula had been a home to various indigenous animistic communities for as far back as 500,000 years ago.

The most recent and accurate theory about the origin of the
Tai people stipulates that
Guangxi province in China is really the Tai motherland instead of
Yunnan province. A large number of Tai people, known as the
Zhuang, still live in Guangxi today. Around 700 AD, Tai people who did not come under Chinese influence settled in what is now
Dien Bien Phu in modern
Vietnam according to the
Khun Borom legend. From there, the Tais began to radiate into northern highlands and founded the cities of
Luang Prabang and
Chiang Saen.
Migration of Bamar
From Wiki
Bamar people - Wikipedia, the free encyclopedia
The Bamar are of East Asian descent, and speak a Sino-Tibetan language (related to Tibetan, and more distantly to Chinese). They migrated from the present day Yunnan in China into the Irrawaddy River valley in Upper Burma about 1200–1500 years ago. Over the last millennium, they have largely replaced/absorbed the Mon and the earlier Pyu, ethnic groups that formerly dominated the Ayeyarwady valley
Peopling of SE Asia and Southern Chinese
Earlier wave of migration suggested by genetist that human move from SE Asia to China. But historically evidences indicates that there is a reverse migration, from the East to SE Asia.
Migration pattern of East Asia and SE Asia are still a contention topic. The ancient people of Southern China moved to SE Asia and dominated them linguistically and culturally in later stage. They produced mestizo. While the remaining people of Southern China mixed with Northern Chinese.
Looking at Cavalli-Sforza, Northern Chinese are indeed far apart from Southern Chinese.
