I found that out about Oriental a few years ago.
The problem is “Asian” isn’t specific enough. It’d include Indians.
Oriental was a perfectly fine word for... those from the Orient.
It’s interesting the ‘moving target’ of the PC police. Negro was preferred by black folks. Then black. Then African-American. I’m sure A-A will be offensive to blacks in about 20 years.
Of course, no one’s ever “offended” by any of this until they’re told they should be.

People aren’t Oriental. Objects are Oriental.
