President Trump is visiting Beijing to meet with Chinese President Xi Jinping this week. Michigan lawmakers are warning him against agreeing to any deals that would allow Chinese electric vehicles into the U.S.

While they are not currently available in the states, President Trump suggested he may be open to allowing them during a visit to the Detroit Economic Club earlier this year. The EVs have become popular, low-cost sellers in Europe and are now available in Canada and Mexico.

Legislation has been introduced in Washington to ban sale of the vehicles. That includes a bill co-sponsored by Democratic Michigan Senator Elissa Slotkin and Ohio Republican Bernie Moreno.

Slotkin argues that having those models on U.S. roads driving near military bases and civilian infrastructure could be a security risk.

“Taking all that data, all that video, all that mapping and sending that back,” says Slotkin. “As someone who’s from the Pentagon, that is the exact detailed information an adversarial nation loves to have in their war planning.”

While Slotkin acknowledges that major tech companies, such as Google, are already collecting people’s data, she argues those companies must follow U.S. laws when handling that information.

Another concern is the impact it could have on American manufacturers, who would stand to lose out on sales.

Republican John Moolenaar represents Michigan’s 2nd Congressional District. He warns that one of the factors keeping Chinese vehicle prices down are unethical labor practices in the country.

“Chinese companies use slave labor to undercut the fair wages of hard-working Americans,” says Moolenaar.

Lawmakers say the U.S. can’t compete with the way the Chinese government subsidizes their auto industry. They argue that creates artificially low pricing for Chinese products that  American companies can’t compete with.
