Japan’s automakers’ lobby said on Tuesday it was dismayed by President Trump’s declaration that some imported vehicles and parts posed a threat to U.S. national security, as the industry braces for a possible rise in U.S. tariffs.

Trump made the unprecedented designation of foreign vehicles on Friday but delayed for up to six months a decision on whether to impose tariffs to allow for more time for trade talks with Japan and the European Union.

“We are dismayed to hear a message suggesting that our long-time contributions of investment and employment in the United States are not welcomed,” said Akio Toyoda, chairman of the Japan Automobile Manufacturers Association.

“As chairman, I am deeply saddened by this decision,” Toyoda, president of Toyota Motor Corp, said in a statement.

Most of Japan’s major automakers operate plants in the United States. At least half of the cars and trucks sold in the country by Japan’s top three carmakers are made in the United States.
