President Donald Trump is facing pressure from U.S. hospitals and generic drugmakers to exempt medical goods from his new tariffs on Chinese imports, as they join big pharma lobbyists who have said such trade barriers will cause shortages of medicines and higher prices in the United States.

After a 10 percent tariff on Chinese products took effect on Tuesday, China announced retaliatory measures, including tariffs and an investigation of Google.

The world’s two largest economies did not cut a deal to avert sweeping U.S. tariffs, which came into effect after midnight. Beijing immediately retaliated.
