I think it has to do with genetics too, ie relative length of limbs to the torso, ratio in lengths between different parts of limbs, and the composition of muscular fiber types. In case of swimming, increased access to pools as well as popularity definitely unlocked Chinese potential in that field, but I think Chinese should continue to do well in weightlifting. At the gym I used to go to, frequently used to see stick-thin Chinese kids squatting over 300 lbs and deadlifting close to 500 lbs. And these kids aren't even weightlifters!I expect China to get better at swimming as the country gets richer and more kids get pool time to showcase their talents. On the other hand, I expect Chinese efforts at sports like weightlifting to suffer somewhat as that sport relies on poor rural folk throwing thier kids to the wolves in order to get the talent pool we have there.
More interesting sports to keep an eye on as living standards increase and urbanization continues is how long dominance in diving can last and the trajectory off the gymnastics teams.
