President Trump said Monday that he will have discussions in the future with Chinese President Xi Jinping and Russian President Vladimir Putin to halt the “uncontrollable arms race.”

“I am certain that, at some time in the future, President Xi and I, together with President Putin of Russia, will start talking about a meaningful halt to what has become a major and uncontrollable Arms Race,” Trump tweeted Monday morning. “The U.S. spent 716 Billion Dollars this year. Crazy!”
