TOKYO (AP) — Japan's government warned in a report Friday that a higher US tariff on auto imports could backfire, jeopardizing hundreds of thousands of American jobs created by Japanese auto-related companies, raising prices for US consumers and devastating the US and global economy.

Japan submitted a position paper Friday to the US Department of Commerce, according to the Japanese trade ministry. In May, Trump ordered the department to conduct an investigation to determine if higher tariffs on foreign-made vehicles and auto parts were justified on national security grounds.

The move outraged Japanese automakers, which have invested billions of dollars in US plants that directly employ tens of thousands of workers.

Any trade restrictions, if imposed, would increase costs for US consumers and "could seriously affect" the jobs, the report said. It said the measures would put a brake on global trade, seriously disrupt the market and put global free trade "at great risk."It said US automakers would lose competitiveness and export markets would shrink, affecting US auto-related industries in and outside the country, and "eventually undermine the entire US economy."Japan said up to 624,000 people could lose their jobs in the US if a 25 percent tariff were levied on automobiles and auto parts and other countries took retaliatory measures, citing a study by the Peterson Institute for International Economics.

Already hit by increased US steel and aluminum tariffs, Japan has told the World Trade Organization it may levy retaliatory tariffs on US goods totaling about 50 billion yen ($450 million) a year.

Japan, in the report, alleged that "broad trade restriction measures on automobiles and auto parts in the name of security raise serious questions about the compliance with the WTO agreements." Possible rebalancing or retaliatory measures from other countries could also damage US manufacturing and agricultural industries, it said.

The report said Japanese auto-related companies have played a vital role in contributing to the growth of the US manufacturing base since the 1980s. They have created over 1.5 million jobs across America and produce about 3.8 million cars in the US, it said.

Japanese companies have invested over $48 billion in the US, sustaining jobs, developing human resources and competitiveness, and contributing to American society like any US company, the report said.
