I'd be leaning toward Twitter at the moment...
I don't see this as much progress except that a willingness to talk is inherently progress of a sort. But clearly Russia wants to (1) keep the Donbass region, and (2) keep Crimea as well. Ukraine wants to retain the former and recover the latter. Unless one side or the other is willing to settle for one and release the other to the opposition I don't see much of a compromise possible, and of course in the view of supporters of both sides, no such compromise is morally justifiable in any case. Ergo an impasse that is going to be difficult to resolve. For now.
Lol. I think you're kind of late for that train...
Russia had four demands in March 2022 to end the war. Talks were progressing until the UK stepped in and said the terms were unacceptable. Now that Putin officially annexed the regions of Donetsk and Luhansk, known together as the Donbas in eastern Ukraine, along with two other regions after holding plebiscites, there is not much to negotiate.
Russia wants Ukraine to stop all military action
Russia wants Ukraine to change its constitution to enshrine neutrality
Russia wants Ukraine to acknowledge that Crimea is officially Russian territory
Ukraine must also recognise Donetsk and Luhansk as independent states
I think Russia considers a land bridge to Crimea as being part of “Crimea”, so that still means Kherson and Zaporizhzhia.
