European travelers are reducing trip plans to the United States during this year's summer season by 10 percent amid sentiment headwinds against U.S. President Donald Trump's policies, Bloomberg reported, citing a report from a British tourism consulting company.

Travel from Canada to the U.S. has also plummeted, with flight bookings during the May-July period down 33 percent, according to a recent forecast released by Tourism Economics, part of Oxford Economics.

As of April, international inbound bookings to the U.S. in May had dropped 9.5 percent year on year, and trips planned for June and July had fallen 10.8 percent and 13 percent, respectively, according to the company.

It expects international arrivals at the U.S. to decline 8.7 percent in 2025 and the spending of international visitors to decrease by $8.5 billion, down 4.7 percent from last year.

"These declines mark a stark contrast to our prior expectations for a continuation of post-pandemic growth this year," said the company.

Trump's tariff policies on longstanding trade partners, such as Canada and the European Union, have contributed to "sentiment headwinds," it said. The Trump administration's posturing, well-publicized border incidents and national advisories warning of the risks of travel to the U.S. have also affected demand, it added.
