BAKU, Nov 23 (Reuters) - Country delegates at COP29 met for a plenary Saturday night to agree on some aspects of this year's negotiations, while their teams continued to work on the summit's centerpiece topic: agreeing a new target for annual climate finance.

Countries agreed on a deal to inject at least $300 billion annually in humanity's fight against climate change, aimed at helping poor nations cope with the ravages of global warming at tense United Nations climate talks in the city where industry first tapped oil.

A draft deal at the U.N. Climate Change Conference calls for wealthy nations to give developing ones $250 billion a year starting in 2035.
