"Rather than remedy its misconduct, China has chosen to harm our farmers and manufacturers", Trump said, adding that he had instructed the United States trade representative to determine whether tariffs on an additional $100 billion in goods were warranted and, "if so, to identify the products upon which to impose such tariffs".
"We do not find ourselves in a trade war with China - the war was lost many years ago by foolish or incompetent people who represent the US", wrote Donald Trump in Twitter. China has promised to respond in kind, but it would be unable to match that amount since it imported only $130 billion of USA goods previous year. The chief target was China, which answered with tariffs on USA pork, fruit and nuts.
China also has threatened tariffs on US automakers. China wasted no time in firing back with 25-percent tariffs on imports of 106 USA products, including soybeans, automobiles, chemicals, and aircraft.
Treasury Secretary Steven Mnuchin said there's a "potential for a trade war" with China, but expressed hope that the world's two largest economies can work out their differences. If the Chinese earn fewer dollars selling into the United States market, they will have fewer dollars to buy USA exports; both imports and exports will then fall. United States stock futures ESc1 fell 1 percent and the dollar dipped against other major currencies. That is likely to cause President Trump political problems in farm states, but it also risks raising food costs within China.
"I'm not saying there's not going to be any pain", he told WABC radio in NY, but "we're going to be much stronger for it".
Mr Kudlow, who has repeatedly sought this week to soothe markets with mention of possible talks, told Bloomberg Television there were always ongoing discussions on trade between the USA and China but that negotiations on the tariffs had not begun.
Despite the mounting tension, the USA president said his country is not in conflict, Bloomberg said.

The president accuses China of stealing US intellectual property and other violations of global trade rules.
China also urged the European Union to join it in taking a clear stance against USA protectionism, calling for Brussels and Beijing to "jointly preserve the rules-based multilateral trade order", said Zhang Ming, head of the Chinese mission to the EU. The U.S. semiconductor industry relies on China for about a quarter of its revenue.
While rising trade tensions have roiled markets, experts said the greater implication for Asia should the tariffs take effect is the risk to economic growth.
He also said no negotiations were likely in the current circumstances.
But if this spirals into a bigger conflict between the world's two biggest economies, it's worth keeping something in mind: In a trade war, the usual rules of commerce may not apply. And that's before you account for the Chinese government's reluctance to put tariffs on goods that might carry some political or strategic cost.
"We are on a risky downward spiral and American families will be on the losing end", Shay added in a statement, urging Trump " to stop playing a game of chicken with the U.S. economy".
