The involvement of China is seen as a big diplomatic prize – it had been invited to the Copenhagen talks in June but did not attend.
The official said there was agreement that working groups would be set up to develop details of key themes prominent in Zelenskiy’s 10-point peace formula while a parallel ambassadors group would continue technical work on the issues.
Working groups would investigate solutions in relation to global food security, nuclear safety, environmental security, humanitarian aid, the release of prisoners of war and kidnapped children that would then “feed into future work of this group at national security adviser level”, the source said.
In parallel a separate ambassadors group in Kyiv would continue technical work.
The talks are designed to find a viable basis for a meeting of heads of state, with sources saying a date was “still a bit up in the air but before the end of the year was considered plausible”.
