More countries are opposing U.S. President Donald Trump's proposed tariffs on steel and aluminium.

Japanese Minister of Economy, Trade and Industry Hiroshige Seko repeated on Tuesday that Japanese steel and aluminium exports are not affecting America's national security but are helping America's economy. He declined to comment on possible retaliation. A government source said any steps Japan does take in response to U.S. tariffs would be consistent with rules of the World Trade Organisation. The European Union on Monday threatened to take retaliatory action. EU said U.S. Levi's jeans and bourbon could be hit with a 25 percent import tax. Harley-Davidson motorcycles are also on a draft list of American goods to be taxed. Meanwhile Brazil filed a protest Monday with the WTO against the U.S. tariffs plan on steel imports and urged the White House to reconsider its decision.
