That’s not correct.
The word „Farang“ in Thailand came up in Thailand (nowhere else) due to the inability of Thais to pronounce the word francais. The French were the first to set foot into Thailand. Thais called them farangsai because they can’t pronounce 2 consonants (f + r) without a vocal in between. After that, they developed a shortcut, leaving the last syllable behind.
The word here in Thailand clearly refers to caucasians, no blacks, no asian foreigners, no arabs or any other race.
