"It's going to be a long-term contract between the U.S. armed forces and the fisheries and co-ops here in Japan," Emanuel said. "The best way we have proven in all the instances to kind of wear out China's economic coercion is come to the aid and assistance of the targeted country or industry," he said. The first purchase involves just shy of a metric ton of scallops, a tiny fraction of more than 100,000 tons of scallops that Japan exported to mainland China last year. Emanuel said the purchases - which will feed soldiers in messes and aboard vessels as well as being sold in shops and restaurants on military bases - will increase over time to all types of seafood. The U.S. military had not previously bought local seafood in Japan, he said. The U.S. could also look at its overall fish imports from Japan and China, he said. The U.S. is also in talks with Japanese authorities to help direct locally caught scallops to U.S.-registered processors.
