President Trump Donald John TrumpBiden leads Trump by 36 points nationally among Latinos: poll Trump dismisses climate change role in fires, says Newsom needs to manage forest better Jimmy Kimmel hits Trump for rallies while hosting Emmy Awards MORE on Wednesday said that Japan uses something called a “bowling ball test” to keep American car companies from selling to Japanese consumers.

In remarks on trade policy given at a private GOP fundraising dinner, the president ripped Japan and other U.S. allies for taking advantage of the United States, according to The Washington Post.

“It’s the bowling ball test,” he said. “They take a bowling ball from 20 feet up in the air and drop it on the hood of the car. If the hood dents, the car doesn’t qualify. It’s horrible.”

Trump may have been joking and using a bit of hyperbole with the remark.

The Post noted that “it was unclear what he was talking about.”

U.S. auto companies have long argued that Japan imposes difficult rules and barriers to prevent more U.S. cars from selling in Japan.

Japanese companies account for nearly 40 percent of auto sales in the United States on an annual basis, according to The Atlantic.

Ford pulled out of Japan in 2016 after selling around 5,000 cars there annually. GM sold about 1,000 cars there in 2016, which is about what some Japanese companies can sell in a day in the U.S.

In the same speech on Wednesday, Trump also said he made up facts in a previous meeting with Canadian Prime Minister Justin Trudeau.

Trump told those at the dinner that he insisted that the U.S. had a trade deficit with Canada, but did not know if that actually was the case, according to the Post.
