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.

The COP29 summit in Azerbaijan has reached an agreement to provide at least $1.3 trillion annually through 2035 to poorer countries to help them fight climate change, with at least $300 billion to come from mainly industrialized nations.
