WASHINGTON - The US tariff rate for some countries will rise to 15 per cent or higher from the newly imposed 10 per cent, US Trade Representative Jamieson Greer said on Feb 25, without naming any specific trading partners or giving further details.

Mr Greer told Fox Business Network’s Mornings With Maria programme that the Trump administration does not intend to raise tariffs on Chinese goods above current levels as President Donald Trump plans to travel to China in the coming weeks.
