The president's optimism comes just after a day since he publicly declared himself a \"Tariff Man,\" and stood by his protectionist trade policies even after stocks fell nearly 800 points amid confusion over the result of Trump's meeting with Chinese President Xi Jinping.

“China officially echoed President Donald Trump’s optimism over bilateral trade talks. Chinese officials have begun preparing to restart imports of U.S. Soybeans & Liquified Natural Gas, the first sign confirming the claims of President Donald Trump and the White House that......
