With laser hair removal, is there a way to have treated area blend into surrounding finer hairs to create a more natural look?

Natural techniques for laser hair removal what you're describing can be achieved for this depends upon the skill and experience I Have the person doing the laser hair treatment.

Hi Jiiin.  What you are asking for usually does not happen.  What normally happens is that instead of having a clear border, the hair usually "fades" away from an area where it is being removed (coarse/dark hair) to an adjacent area that has fine hair.  In between those areas is usually medium hair that sometimes responds and sometimes does not so you end up with a slow transition from the area where you had the dark hair to the area that you had the peach fuzz.  What you are asking to do is difficult because the laser either removes the hair or does not, rather than just removing some as you have asked for.  For examples of before and after pictures of Asian skin laser hair removal in Los Angeles, click the link below.
