Japanese automakers, led by Toyota Motor President Akio Toyoda, had more harsh words for U.S. President Donald Trump on Tuesday after he labeled international auto imports a threat to national security last week.

"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 Toyoda, chairman of the Japanese Automobile Manufacturers Association.

Toyoda said that he was "deeply disappointed" in Trump and that trade restrictions "would deliver a serious blow to the U.S. auto industry and economy."

The group released new data that shows the companies have collectively invested about $51 billion in manufacturing in the United States over the last several decades. The group also estimates its members have created almost 94,000 manufacturing jobs at their U.S. plants and more than 1.6 million indirect jobs, like at dealerships and suppliers in the U.S.

"These numbers speak for themselves about JAMA member companies' long history of local contributions and commitment as U.S. corporate citizens, and we are certain that neither imported vehicles and parts nor our American operations 'threaten to impair' the U.S. national security," Toyoda said.

Direct U.S. employment at Japanese manufacturers is at an all-time high, JAMA USA General Director Manny Manriquez said. From 2011 to 2018, direct employment at Japanese automakers operating in the U.S. grew by nearly 29%, compared with the overall growth rate of 8% across all U.S. manufacturing jobs.

"We think this is an incredible achievement for international car companies," Manriquez said. "We've got a long history of continuing to strengthen the manufacturing base in the U.S."

Japanese automakers have a wide reach in the U.S., according to the JAMA data.

JAMA manufacturers, including Honda, Mazda, Mitsubishi, Nissan, Subaru and Toyota, have 24 manufacturing plants, 45 research and development design facilities, and 39 distribution centers across 28 states in the U.S.

Japanese manufacturers today build more than a third of the vehicles manufactured in the U.S., according to the data. In 2018, JAMA manufacturers built 3.7 million vehicles and 4.4 million engines. More than 420,000 cars and trucks built by Japanese companies were exported from the U.S. that year.

JAMA said Japanese brands have produced more than 84 million vehicles in the U.S since 1982 and purchased more than $1 trillion in auto parts that were built in the U.S. since 1986.
