GENEVA, March 7 (Reuters) - Major trading partners of the United States expressed both commercial and systemic concerns about its tariffs plan on Wednesday and said they feared tit-for-tat trade actions, a World Trade Organization (WTO) spokesman said.
China kicked off the debate about the planned tariffs on steel and aluminum at the closed-door meeting. Delegations taking the floor included the European Union, Canada, Turkey, Russia, Australia, South Korea, Japan, Mexico, India and Brazil.
"We fear that the United States may be opening a Pandora's Box that we would not be able to close," a trade official quoted Canada's ambassador as saying. (Reporting by Tom Miles; writing by Stephanie Nebehay)
