This kind of question is dumb. It imagines there is an entity called "China" that's tasked with feeding 1.3B people.
In reality, it's just 1,300,000,000 individuals tasked with feeding themselves, just like anywhere else in the world. We do it by division of labor. Some grow food, others build goods, others provide services. We all trade with each other so everyone can specialize at what we do best.
It's no different if the nation border happens to enclose 1.3B Chinese nationals or 300K Icelandic ones.
