EU-U.S. talks that could prevent the United States imposing punitive car tariffs have made some progress, but Washington must decide if it wants to negotiate with Brussels on a broad removal of import duties, the EU trade chief said on Monday.

EU countries last month cleared the start of formal trade talks with the United States on two fronts: cutting tariffs on industrial goods, and making it easier for companies to show their products meet the standards of the EU or U.S. market.

EU Trade Commissioner Cecilia Malmstrom said the two sides had made progress on the latter, conformity assessment, as well as discussing potential for regulatory cooperation, which could avoid the need to test on both sides of the Atlantic.
