China is currently occupying Tibet, which never consented to the occupation and has invaded Vietnam 30 times. It ruled Vietnam for about 2 centuries starting about 600. China eventually had to leave Vietnam, but many other groups ceased to exist as a consequence of Chinese expansion. Here are some:

the Baiyue were a vast umbrella of diverse, non-Sinitic indigenous coastal tribes who inhabited Southern China and northern Vietnam.

The Xianbei were an ancient nomadic Proto-Mongolic people from the northern steppes.

The Di and Jie were two of the ancient "Five Barbarian" (Wu Hu) nomadic tribes of northern and western China during the Han and Jin periods.

The Dian Kingdom were an ancient, sophisticated indigenous southwest culture located in modern-day Yunnan province.

The Tujia were an indigenous group of the Hunan-Hubei region. Centuries of inward Han migration and intermarriage have resulted in the Tujia becoming culturally and structurally indistinguishable from their Han neighbors.
