Comment on the Global Food Trade

Looking it up just now, it does appear that the U.S., does in fact import many foods from China, including fruits, vegetables, spices, tea, snack foods, fish, and shrimp. In turn, the United States exports many foods to China, including corn, soybeans, wheat, rice, dairy, beef, pork, tree nuts, and sorghum.
Is this a bad thing? Is it some sort of tragedy that the layout and skill set of the U.S. makes us better at growing bumper crops of corn, where the Chinese are better at harvesting and processing shrimp? Or is just another attempt to upset ill-informed people?
