The US is considering a proposal to redraw Ukraine's administrative borders as part of a possible peace deal with Russia.
The proposal, described as a "cartographic fudge", would redraw the administrative boundaries of Donetsk and Luhansk.
This would allow Russia to claim full control of both regions without Ukraine giving up the remaining cities it holds.
However, significant disagreements remain over territorial control, security guarantees and the broader terms of the settlement.
