Charlie and Olive are 3/4 Asian (1/2 Korean, 1/4 Japanese) and 1/4 white, so they look more Asian.
Most people think that Charlie is 100% Asian, but Asians can usually tell that he is a little bit mixed.
Olive on the other hand looks 100% Asian.
Mixed Asian babies tend to look less Asian as they get older though, so I'm sure Charlie and Olive's faces will change!
