European and American negotiators concluded their latest round of trade talks this Friday and renewed their commitment to have TTIP signed before the US presidential election at the end of this year.“We are now at an advanced stage of negotiations, but of course a lot of work needs to be done,” said the European Union’s chief negotiator Ignacio Garcia Bercero at a news conference in Brussels this Friday. He added that he hoped to close the deal “with the current US administration, provided of course the substance is right”.
