Another false argument. We sell treasuries to whoever will buy them in order to support the government's deficit spending - mostly spent on "entitlements", defense, and infra-structure here in the US. The fact that China buys US treasuries, has absolutely nothing to do with Chinese products being sold in Walmart and Target.
The connection is that much of the money the government gets from any kind of borrowing goes to entitlements. What do the entitled spend their money on? Products that are largely made in China.
