WASHINGTON, April 29 (Xinhua) -- The White House has criticized retail giant Amazon's decision to display tariff costs alongside the price of its products.

Responding to a report of the planned Amazon move, White House Press Secretary Karoline Leavitt on Tuesday called the move a "hostile and political act." She made the remark during a press briefing with Treasury Secretary Scott Bessent.

"Why didn't Amazon do this when the Biden administration hiked inflation to the highest level in 40 years?" Leavitt asked.

She urged Americans to "buy American."

Earlier Tuesday, Punchbowl News reported that Amazon intends to display the tariff costs imposed under President Donald Trump's administration as part of each product's price.

"Amazon doesn't want to shoulder the blame for the cost of President Donald Trump's trade war. So the e-commerce giant will soon show how much Trump's tariffs are adding to the price of each product," the report said, citing a source familiar with the plan.

Many retailers have voiced concerns about the additional costs imposed by tariffs. In a report earlier this month, Best Buy executives said new tariffs "could increase costs, disrupt our supply chain and/or impact the availability of underlying technology critical to our operations."
