"If the conditions for the international agreement are not favorable for us we may not join such an agreement," Alexander Pankin, deputy head of the Russian delegation at U.N.-led December 1-12 climate negotiations in Poland, told Reuters.
If a new U.N. climate pact meant to be agreed in Copenhagen at end-2009 was unfair and failed to set comparable commitments for countries according to their economic and social standing, Russia would not sign, he said.
"If you are better off than me, why should I make a stronger commitment than you," he said.
