* EU Commission appeals for Trump to abandon tariffs
* Says can prepare retaliatory measures if needed (Adds quotes from Timmermans, amends slug to distinguish from USA-TRADE/EU item)
DILLINGEN, Germany, March 12 (Reuters) - Europe does not understand the logic of proposed U.S. steel tariffs on the basis of national security concerns but will prepare retaliatory measures if necessary, European Commission First Vice President Frans Timmermans said on Monday.
Last week, U.S. President Donald Trump pressed ahead with import tariffs of 25 percent on steel and 10 percent for aluminium, exempting Canada and Mexico and offering the possibility of excluding other allies.
Describing the dumping of steel and aluminium in the U.S. market as “an assault on our country,” Trump said that the best outcome would be for companies to move their mills and smelters to the United States. He insisted that domestic metals production was vital to national security.
Timmermans said that if the reason for Trump’s measures is security, then there should be no reason to impose these tariffs on Europe.
“How is European steel a threat to the U.S.?” Timmermans said at a steel conference held in Dillingen, Germany. “We have a different relationship on matters of national security than the U.S. has with China.
“If it becomes necessary, we will prepare countermeasures, but these will be conform to World Trade Organisation rules,” Timmermans added.
“I think in Trump’s view of the world, when the other person loses, he wins. But in this situation there will be no winners.” (Reporting by Edward Taylor Editing by Arno Schuetze and Mark Heinrich)
