President Donald Trump announced Thursday that the US will soon impose tariffs on billions of dollars of Chinese imports, a move that could eventually trigger a trade war.

The tariffs, which function as a tax on imports, come in response to a Trump administration investigation into the China’s theft of US intellectual property, or IP. For instance, the country hasforced businesses to move their patents to China or disclose their trade secrets to do business there.

Trump will impose tariffs on imports of more than 100 different Chinese goods and hit industries from biopharmaceutical to robotics to rail equipment. A full list of products will be released in 15 days according to White House officials, which will give businesses time to petition for certain items to be excluded. The statement will also limit certain Chinese investments into the US.

Chinese officials have already signalled they will respond with tariffs of their own.
