President Trump retaliated against China’s new tariffs Friday afternoon, declaring that he would increase existing and future levies on Chinese goods.

“Starting on October 1st, the 250 BILLION DOLLARS of goods and products from China, currently being taxed at 25%, will be taxed at 30%,” he tweeted.

“Additionally, the remaining 300 BILLION DOLLARS of goods and products from China, that was being taxed from September 1st at 10%, will now be taxed at 15%. Thank you for your attention to this matter!”

Tariffs on the $300 billion worth of imports were originally all going to be imposed at the start of September — but Trump later pushed back the launch date for many consumer products until December.

China earlier Friday announced new tariffs of 5 percent and 10 percent on $75 billion of US products, deepening a conflict over trade and technology that threatens to tip a weakening global economy into recession.

China will also go ahead with previously postponed import duties on US-made autos and auto parts, the Finance Ministry announced.
