Thanks for writing in. In MBA applications there is not a hard and fast rule about what your GMAT must be, however a 610 is well below the median scores of the schools you listed, so you would be applying at a disadvantage. Of that list it seems that HKUST is your best chance for admission, but you'll need to counteract that GMAT score with strong work experience and clear goals, regardless of where you apply.
Best of luck,
