Following Monday's suspension of talks on points raised by the African group, supported by the wider G77-China bloc of developing countries, some sessions ran long into the night as negotiators tried to make up lost time.

The Danish conference hosts had been accused of trying to sideline negotiations on the Kyoto Protocol by packaging discussion of outstanding difficult issues from across the various strands into a single informal session.

Developing countries are adamant that developed nations still inside the protocol - all except the US - must commit to further emission cuts under its aegis.

After discussions with the Danes and UN climate convention officials, the informal talks were split as the G77-China bloc had demanded.

One group, chaired by Germany and Indonesia, is examining further emission cuts by developed nations under the Kyoto Protocol.

Another, chaired by the UK and Ghana, is looking at long-term financing to help poorer countries develop along "green" lines and protect themselves against impacts of climate change.
