I don't see any age signs so probably recent.
To me it looks like done in Yuan Qingbai style but I suspect it could be Korean maybe.
What do you think?
Modern in my view, neither Yuan nor Korean. Both would have a different base.
I would think Japanese, mid 20th century, I think, I have seen plates like this from the 50s and 60s, I could be wrong but that would be and educated guess.
I thought Japanese too but can't rule out other Asian countries as well.
