My DIL on 23andme show about .5 Chinese, .4 Korean and 1.7 unassigned and 97.4% Japanese. On WeGene they show 99.6% Japanese and .28 Korean. That is so very minor its pretty much the same.
I have no idea which to trust, Might need to rely more on the paperwork. Or do a transfer to GEDmatch and then look and see where his matches are from. If most of his matches are Chinese, Korean, Japanese then East Asian. If they are Filipino or Thai then probably South Asian. This will require a little digging.
