LONDON - British Prime Minister Keir Starmer spoke to Japanese Prime Minister Shigeru Ishiba on Thursday, and both agreed that a trade war does not benefit anyone.

This meeting happened as the United States kept a 10 percent tariff on most countries, as well as a 25 percent import tariff on steel and aluminium, and car parts.

Washington's controversial new set of tariffs has stirred tensions in recent weeks, hitting global markets hard, sparking backlash from other countries and drawing widespread criticism from economists and investors.

According to a Financial Times report, Starmer acknowledged earlier that it is unlikely the United States will remove the new 10 percent tariff on all British imports, and the prime minister is trying to persuade the US president to lift the 25 percent tariff on British cars.

British economists have warned that mounting uncertainty, weaker exports, and rising costs are likely to weigh on growth and employment across the country's key sectors.

Also on Thursday, Japan announced plans to send Economic Revitalization Minister Ryosei Akazawa to the United States for tariff negotiations as early as next week.
