China increases inspections of U.S. food imports.

China increases inspections of U.S. food imports: China sharply increased inspections this week of imported U.S. food, escalating its spat with Washington over product safety and leaving U.S. beef piling up in warehouses and delaying shipments of black pepper and other goods. Authorities who used to inspect as little as 5% of imported goods now check every shipment of American poultry, snack foods and other products.
