I'm 6'1" I've been able to dunk since 5'11" or so. if you want to dunk you gotta work on your ass and you gotta do explosive exercises: sprints, stadiums, jumping etc.
I trained with jump shoes after my freshman year of college with a couple of other dudes and could dunk after that. 90 minutes of sprints/jumping until you puke, stretching and weights 5 times a week. the good thing is that once you have the muscles in your ass and calves you'll have the hops forever as long as you stay in reasonably good shape

I'm 6ft, and I play basketball (currently injured and recovering from a knee reconstruction), I can't dunk, but I can touch the ring (regulation height).
from what i've seen most average height guys in good shape can get up around the rim. IMO anyone who's at least average height has the potential to be able to dunk at least a volleyball if they know how to properly train to increase their vertical. The larger stumbling block IMO is that asian guys have small hands, if you want to dunk it helps to be able to get a good grip on the ball, otherwise you're losing a couple inches cradling the basketball.
and "asian" doesn't really mean anything. you're talking about a 1.7 billion person genepool there's more variation between a korean dude and a samoan than between the average white and black guy in the US (the majority of whom are mixed). from playing sports with lots of different asian dudes tho, there are definitely things you see between the asian races for example the average height in korea now is 5'10" (same as americans) and they tend to be stockier than chinese guys. japanese dudes of course are like all 5'7" and weak up top but for some reason I've met a lot of japanese dudes who are really fast and a lot who can really sky for their height. I dont know why that is... a friend of mine has a theory that although koreans are taller they have longer torsos and shorter (proportional) arms while japanese are smaller and more proportioned so they can jump higher LMAO
but yeah anyone can increase their vertical so dont believe that crap that asians cant dunk. dunking in a game tho is a whole other level. I've only seen a couple asian guys who could do that easily
