Let's compute locations with dominant Arabs communities and the majority countries they are from. From what I was told and share as below. Feel free to share others and add to the list below:-

1) SERI KEMBANGAN - ONE SOUTH PROJECT - Yemeni, Iranians

2) SERI KEMBANGAN - Sky Villa

3) BUKIT BINTANG

4) Pudu - Myammar

5) Mont Kiara - Korean

@ahb_som thanks for the input, want to change title to foreigner/expat communities but can't

6) Langkawi - Pantai Chenang -- Arab 'ownership'

@carmenfoong A fact.

How about heavily China populated? 

@sam92.... good idea

@carmenfoong I notice more china are coming in via mm2h, yet to determine where the majority of them are residing at the moment. Any experts can share the insight will be very helpful.
