Trump says EU bid to end auto tariffs 'not good enough': Report

President Donald Trump has reportedly rejected as "not good enough" a European Union proposal scrapping tariffs on automobiles, a move which threatens to amplify a simmering trans-Atlantic trade dispute.

Just hours earlier, the EU Trade Commissioner Cecilia Malmstroem had said the bloc was "willing to bring down... our car tariffs to zero" provided that the United States did the same.

"It's not good enough," Trump told Bloomberg News yesterday in an Oval Office interview, speaking of the Brussels offer.

"Their consumer habits are to buy their cars, not to buy our cars." The White House in July sought to defuse the trade tiff when Trump and European Commission President Jean-Claude Juncker met and pledged to work towards a limited trade accord that would eliminate customs duties, but excluded the automobile sector.

Trump also compared the EU to China. He has reportedly threatened to slap import taxes on $200 billion in Chinese goods, as a trade war escalates with Beijing.

"The European Union is almost as bad as China, just smaller," Trump said.

He also warned that he could pull the United States out of the World Trade Organization.

"If they don't shape up, I would withdraw from the WTO," Trump said of one of the key anchors of the post-World War II multilateral trading system that the United States helped construct.

At a time when Trump's protectionist policies have sparked a wave of trade wars, the institution best placed to help settle trade differences is facing a deepening crisis.

This week Washington blocked the reappointment of a WTO judge, increasing the risk it could soon find itself unable to fulfil its key role in arbitrating disputes.
