IIRC-—MALAYSIA has the highest MUSLIM population of any country in the world.
Nope
There are about 20 million Muslims (and 13 million non-Muslims) in Malaysia. In other words slightly more Muslims than there are in Russia.
The largest Muslim population is in Pakistan, followed by Indonesia, India, Bangladesh, and Nigeria.
Malaysia is well down the list. But some semiconductor manufacturers have invested a lot of money there.

I was in Malaysia (Kuala Lumpur) for a little over 3 weeks in 1974, working for Texas Instruments. It was a very nice place back then. Everyone spoke perfect English.
