No guarantee Montreal ozone talks will succeed -U.S.

OTTAWA (Reuters) - Although countries back the idea of eliminating ozone-depleting chemicals faster than originally planned, there is no guarantee that they will agree on a new accelerated timetable at a major conference this week, a senior U.S. official said on Monday. 

Claudia McMurray, U.S. assistant secretary for the environment, said the main problem was working out whether the technical and financial aid available for the developing world would be enough to satisfy countries such as China.
