4 million in their region...but 3 million are spreading...mostly in Indonesia big city. Singapore first President is also from Minangkabau.....many has higher position in Malaysia as well. It is a political and trader ethnic of native Indonesian....Clever people and respected.....None of you see this tribe go overseas for uneducated work....Most funding father of Indonesian are also from this tribe....including one of two of our Independence proclamers...which are Soekarno (Javanese ) and
Muhammad Hatta is Minangkabau. First Prime Minister of Indonesia is also Minang Tribe. This tribe is also known as quite Islamic Tribe....Muhammadiyah which is the Wahhabi type of Islam is actually form by Minang (Sumatrans) and Yogya (Central Java) clerics. Sundanese is also very Islamic......Thats why in Minangkabau (West Sumatra) and Sundanese (West Java)...mostly Islamic parties won there. Today West Java (Sundanese) is lead by the governor coming from the most conservative Islamic Party (PKS)....
This tribe (Minang) has some Arabic link according to China voyager....Arab village are seen in West Sumatra since long time ago. Many Indonesian artist are also coming from this tribe. I doubt they come from Vietnam......because I have pure blood of Minangkabau.....and never heard such story.....but according to Minang old people...they believe they come from Alexandre The Great ...
(I doubt this story....it just maybe Arab traders who are taller than SEA people) but any way Good luck to Vietnamese Friends for bringing this tribe to your thread
