We already have asian DnD elves. The Gith are fucking Asian. All the old art is a hilariously stereotypical Asian caricatures, with a bit of fantasy magic thrown in.

Like all gith, githzerai were tall and emaciated-looking humanoids, but, thanks to their rigid training, had more muscular bodies.[2] They had pale yellow skin, sometimes with greenish or brownish tones. Their skulls were long and angular, with deep-set eyes, flattened noses, and long pointed ears. Typical hair colors included black, russet, and sometimes gray, which male githzerai either shaved or wore in braids. Their facial hair was also carefully groomed.

It's literally chink elves. Their race is split in half between the evil Gith that follow a dictatorship, and the Good ones that follow fantasy Confucianism. Gith have 3 racial classes which are basically kung-fu monks, kung-fu swordmasters, and old guys that meditate so much they get superpowers (enlightened, originally psionicists, but now wizards).

And even if you don't like Gith because they've been turned into a sci-fi race to hide their racial traits, there's plenty of other ones. Yuan-ti, Kenku, kitsune/shapeshifters, Spirit Folk. There's no shortage of eastern representation. Or there was, before they decided to take all the flavor out of those classes so they could pretend they're not distinctly racial too.
