Doha trade talks finally dealing with substance - US

GENEVA Feb 17 (Reuters) - An intensive week of talks among key trading powers was constructive and the long-running Doha negotiations have finally started to deal with matters of substance, the U.S. ambassador to the World Trade Organization said on Thursday.

"My sense is that we're finally starting to do the things we need to do, which is grapple with the really hard issues," U.S. envoy Michael Punke told Reuters after a week of meetings among 11 major WTO members including the United States.
