A member of the so-called Umbrella Group, Canada stated earlier this year that it won't accept the second commitment period under the Kyoto Protocol after its first commitment period expires at the end of 2012.
The Umbrella Group, also including Japan, Australia and Russia, acts as a negotiating bloc in climate change talks that rejects new commitments.
An official in the Chinese delegation told Xinhua that Canada could hardly meet the emission cutting requirement even in the first commitment period of the Kyoto Protocol.
The Kyoto Protocol, an attachment to the United Nations Convention on Climate Change, is the only legally binding treaty in the world that requires developed countries to reduce greenhouse gas emissions.
