President Donald Trump went after China for being “vicious” to the United States on trade issues in a tweet storm Wednesday.

“Every time I see a weak politician asking to stop Trade talks or the use of Tariffs to counter unfair Tariffs, I wonder, what can they be thinking?” Trump tweeted. “Are we just going to continue and let our farmers and country get ripped off? Lost $817 Billion on Trade last year. No weakness!”

“When you have people snipping at your heels during a negotiation, it will only take longer to make a deal, and the deal will never be as good as it could have been with unity,” he continued. “Negotiations are going really well, be cool. The end result will be worth it!”

“China is targeting our farmers, who they know I love & respect, as a way of getting me to continue allowing them to take advantage of the U.S.,” he tweeted. “They are being vicious in what will be their failed attempt. We were being nice – until now! China made $517 Billion on us last year.”

Trump has long been clear about how he feels on trade issues. On Tuesday, he tweeted, “Tariffs are the greatest!” adding, “Remember, we are the ‘piggy bank’ that’s being robbed. All will be Great!” (RELATED: ‘Tariffs Are Great’: Trump Triumphant As Trade Battles Escalate)
