Trump says tariffs on China will be increased to 25% as trade talks stall

President Trump tweeted on Sunday that tariffs on $200 billion of Chinese goods will be raised from 10% to 25% on Friday, as trade talks between the U.S. and China progress "too slowly."

For 10 months, China has been paying Tariffs to the USA of 25% on 50 Billion Dollars of High Tech, and 10% on 200 Billion Dollars of other goods. These payments are partially responsible for our great economic results. The 10% will go up to 25% on Friday. 325 Billions Dollars of additional goods sent to us by China remain untaxed, but will be shortly, at a rate of 25%. The Tariffs paid to the USA have had little impact on product cost, mostly borne by China. The Trade Deal with China continues, but too slowly, as they attempt to renegotiate. No!

The backdrop: In February, U.S. trade representative Robert Lighthizer told Congress that the U.S. had temporarily dropped its plans to raise the tariff rate to 25%, as the two sides inched closer to striking a deal.

• Reality check: Trump has repeatedly claimed that tariffs have caused China to pay billions of dollars to the U.S. treasury. This is incorrect. The tariffs are paid by U.S. importers of affected Chinese goods, not by China's government or by Chinese companies. Importers then either raise costs on consumers, lower their own profit margins or both.

Driving the news: Chinese Vice Premier Liu He — along with a 100+ person delegation — will be in Washington on Wednesday, per the Washington Post, for another round of trade talks. Sources have told CNBC that a trade deal could possibly come as soon as Friday, a day after the latest numbers on the U.S. trade deficit are released, though Trump's latest tweets suggest otherwise.
