Canada's prime minister is reversing his position and will attend the Copenhagen climate-change meeting next month.
Stephen Harper's spokesman Dimitri Soudas said Thursday Harper decided to attend after the U.S. and Chinese presidents announced they were going to the U.N. talks.
The news comes a day after Harper said he would not travel to Copenhagen.
The meeting to work on a new climate-change agreement runs Dec. 6-18, but it's not clear when Harper will attend.
Canada has come under strong criticism internationally for reneging on the Kyoto climate protocol and for refusing to sign on to a new deal limiting greenhouse gases unless developing nations are included.
