US President Donald Trump is set to announce a sweeping plan on Wednesday to place tariffs on potentially trillions of dollars’ worth of goods imported into the United States. It is still not yet known how much the tariffs will be and how many countries and products will be affected, Trump has dubbed the move “Liberation Day”. Trump has already introduced a series of taxes covering steel, aluminium and car imports as well as all goods from China. Trump argues the measures - which make foreign goods more expensive - will help US manufacturers and protect jobs. However, prices could go up for consumers.
