The Han Chinese that live in China do.
Marco Polo did not report that they ate with sticks, which he would have if those he met did.
Then why didn't he report that they ate with utensils? Are you suggesting that they ate with efficient utensils in antiquity, but switched to the use of inefficient sticks just recently? Perhaps when no westerner is around they pull out the hidden forks?
I guess I'm missing your point.
The Han would probably build their superjumbo out of bamboo.
