Wouldn't it be interesting to have more K-pop stars of Uyghur origin ? Manny is a ethnic Uyghur, the first muslim K-pop star from the K-pop boyband "Varsity" (2017 to present). He stood out because of his foreign or mixed race looks.
( A little more historical background on Uyghurs )
In China, Uyghurs are known for their Caucasian or part Caucasian looks in Xinjiang (or East Turkistan or Tarim Basin ). Most of them look mixed race with mostly East Asian looks but many look like White, Caucasian, Middle easterner, Persian, European types. They are hired as models, actress, and play foreigners roles sometimes.
It is said the Original Uyghurs were East Asian invaders that conquered the Xinjiang/Tarim Basin inhabited by Indo-European Iranic people who were Caucasians like neighboring Tajikistan. They ended up intermixing in various degree. Uyghurs from North ended up with more East Asian features while the Southern Uyghurs with more Caucasian features. They named their country East Turkistan but was later conquered by China.
Here is how it's people look like in their traditional dress
