Republican presidential nominee Donald Trump had some harsh words about China's economic conduct in his acceptance speech at the GOP national convention on Thursday night.

"We are going to enforce all trade violations, including through the use of taxes and tariffs, against any country that cheats," Trump said in the speech, which made its way through various media outlets on Thursday afternoon. The Trump campaign also released excerpts of the speech.

"This includes stopping China's outrageous theft of intellectual property, along with their illegal product dumping, and their devastating currency manipulation," he said. "Our horrible trade agreements with China and many others will be totally renegotiated. That includes renegotiating NAFTA to get a much better deal for America - and we'll walk away if we don't get the deal that we want."

Trump also teed off on the Trans-Pacific Partnership (of which China is not a part), accusing presumptive Democratic nominee Hillary Clinton of supporting it.

"The TPP will not only destroy our manufacturing, but it will make America subject to the rulings of foreign governments," Trump wrote. "I pledge to never sign any trade agreement that hurts our workers, or that diminishes our freedom and independence. Instead, I will make individual deals with individual countries.
