Hint.
We don't import the everyday grocery items from China as was being implied.
That wasn't being implied. You appear to be struggling to understand how a more affluent nation might end up spending more money on imports than a relatively poorer nation does, or how it could possible be fair trade if the US is buying more from some country than that country is buying from the US.
The grocery store example was to intended to help you relate to the concept that sometimes when you buy things from somewhere, they don't always buy things from you.
Presumable you eat food, and grocery stores are a fairly common place to obtain food, so I thought you might have some personal experience with shopping at a grocery store to relate to.
Chances are that when you shop at a grocery store, the store doesn't buy as much from you as you buy from them. This means that you have a trade imbalance with the grocery store. That is how a trade imbalance works, when party A buys more from party B than party B buys from party A.
But perhaps you can recognize that even though the grocery store doesn't buy as many groceries from you as you buy from them, it is still a fair trade when you buy groceries, because you receive groceries that are worth more to you than the money you spent on them.
The point is unfair China trade practices.
Some can't even see this or just refuse to acknowledge that fact.
A trade imbalance does not indicate unfair trade practices. The only thing a trade imbalance indicates is who the supplier of goods is and who the purchaser of goods is in a trade relationship.
Just like with the grocery store example, the fact that you buy more from the grocery store than the grocery store buys from you does not mean that the grocery store is engaging in unfair trade practices. It just means that the grocery store is the supplier, and you are the purchaser in your trade relationship with the grocery store.
Likewise, our trade imbalance with China indicates that China is primarily a supplier of goods, and the US is primarily a purchaser of goods in our trade relationship with China.
