The European Union warned Monday it would react "swiftly and appropriately" if Washington imposed trade curbs, after US President Donald Trump accused the bloc of trading "very unfairly" and hinted at such action.
"The European Union stands ready to react swiftly and appropriately in case our exports are affected by any restrictive trade measures from the United States," European Commission spokesman Margaritis Schinas told reporters.
Trump told Britain's ITV channel that the EU has treated the US "very unfairly when it came to trade" and that his many problems with Brussels could "morph into something very big".
In reaction to the Trump interview, Schinas said: "For us, trade policy is not a zero-sum game, it is not about winners and losers. We here in the European Union believe that trade can and should be win-win."
Schinas added: "We also believe that while trade has to be open and fair it has also to be rules based."
Trump delivered the warning during a wide-ranging interview last Thursday on the sidelines of the World Economic Forum in Davos, where he took his "America First" agenda to the global business elite.
In a speech Friday he told the forum that his mantra "does not mean America alone" and hinted that the US could rejoin the Trans-Pacific Partnership, a deal he withdrew from a year ago.
But earlier this month the Trump Administration imposed steep tariffs on imported washing machines and solar panels.
Last year it vowed to impose nearly 300 percent punitive tariffs on airplanes manufactured by Canada's Bombardier.
A bipartisan US trade panel blocked that decision on Friday but the dispute, which has inflamed relations with Ottawa -- and to a lesser degree Britain, where Bombardier has a large workforce -- could be a harbinger for the EU.
