The United States has approached China seeking talks over President Donald Trump's 145% tariffs, a social media account affiliated with Chinese state media said on Thursday, the latest report of possible moves towards negotiations on the levies.

Tariffs on China will remain at their current levels, according to Stephen Miran, a key architect of President Donald Trump’s trade policies. Miran’s comments come at a time when the administration is trying to calm nervous investors but offering mixed signals.

Monthly surveys of Chinese factory managers shows export orders slowed in April as higher tariffs on U.S. imports began to kick in.
