President Donald Trump said he’s "ready to go" with tariffs on $500 billion of Chinese imports, saying the U.S. has been taken advantage of for too long. The $500 billion figure is about the value of Chinese goods imported into the U.S. last year. China accused American officials of making false accusations Thursday as it fired back against a claim President Xi Jinping is blocking talks with the U.S. Earlier, White House Economic Adviser Larry Kudlow said Xi has no intention of making a deal over trade with the Trump administration.
