I'd suggest you double check that. China depends heavily on US Soybeans, rice and fish heads notwithstanding.
I think he is referring to something like a "Japanese Inspection?" A Japanese Inpsection, you see, when the Japs take in a load of lettuce they're not sure they wanna let in the country, why they'll just let it sit there on the dock 'til they get good and ready to look at, But then of course, it's all gone rotten... ain't nothing left to inspect. You see, lettuce is a perishable item...
But In this case the Chinamen really really need our Soy Beans. They went to Brazile (the worlds second largest producer of that little legume) but they still need our beans to feed their livestock and animals so they can feed their peoples..
