US President Donald Trump's administration is proposing additional tariffs of 10% or more to be imposed on its trading partners following a probe into countries importing goods allegedly made with forced labor.

In a report released Wednesday, the US Trade Representative (USTR) said it had found that 60 economies had failed to "impose and effectively enforce a prohibition on the importation of goods produced with forced labor," calling it a "burden" to US commerce.

"This creates a dynamic where American workers are forced to compete globally on an unlevel playing field. We will no longer tolerate this disparity," USTR Ambassador Jamieson Greer said in the document.

The tariff proposal is currently open to public comment and review and is therefore not in immediate effect.

The new tariffs under US trade law could help Trump bypass the Supreme Court ruling in February which stated that his tariffs werelargely illegal.
