Japan's top government spokesperson said on Wednesday that auto import restrictions by Washington would adversely affect the US and global economies.

Chief Cabinet Secretary Yoshihide Suga told reporters that any trade steps should be taken in accordance with WTO rules.

He made the comment after Japan's automakers' lobby said on Tuesday it was dismayed by President Donald Trump's declaration that some imported vehicles and parts posed a threat to US national security, as the industry braces for a possible rise in US tariffs.
