President Trump on Tuesday posted a series of tweets about trade with China.

President Trump on Tuesday warned of new tariffs on Chinese goods.  He said in a series of tweets: "The negotiations with China have already started. Unless extended, they will end 90 days from the date of our wonderful and very warm dinner with President Xi in Argentina."  "Bob Lighthizer will be working closely with Steve Mnuchin, Larry Kudlow, Wilbur Ross and Peter Navarro on seeing whether or not a REAL deal with China is actually possible," Trump continued. "If it is, we will get it done. China is supposed to start buying Agricultural product and more immediately. President Xi and I want this deal to happen, and it probably will." 
"But if not remember, I am a Tariff Man," he further noted. "When people or countries come in to raid the great wealth of our Nation, I want them to pay for the privilege of doing so. It will always be the best way to max out our economic power. We are right now taking in $billions in Tariffs. MAKE AMERICA RICH AGAIN."  News of the tariff truce on Saturday was followed by a surge in China's markets, with notably strong performances for the country's stocks and currencies.  The Wall Street Journal reports that analysts are warning the upward swing could easily reverse "given the lingering uncertainties in trade relations between the world's two largest economies, as well as concerns about the health of China's economy."
