Donald Trump has once again taken issue with Japan’s trade practices, arguing that the country benefits unfairly from selling millions of cars to the United States while doing little to support American exports in return.

Speaking during a Fox News interview aired on Sunday, the former president said Japan needs to open its market more to U.S.-made vehicles and suggested that Tokyo could also help balance trade by increasing its imports of American oil and other goods.

Trump’s remarks come at a time when Japan is trying to avoid steep U.S. tariffs on its car exports, namely a 25% tariff already in place and a possible 24% retaliatory tariff set for July 9. The auto sector is a major part of Japan’s economy, with vehicles making up nearly 28% of its $145 billion in annual exports to the U.S.

The comments highlight Trump’s continued focus on trade imbalances, particularly with key allies, and signal that trade tensions could resurface if he regains political power.
