Importers of US seafood in China are bracing for the impact of the new tariffs imposed by the government, reports Reuters.

Gao Han, a salesman at Beijing Chaoxing Seafood Company, which sells US lobsters, said that his firm was stocking up before the tariffs hit, but that if the issue persisted they’d have to raise prices or shift supply.

“There’s nothing we can do if there’s a trade war,” Gao said.
