Russia-Ukraine updates: US sanctions Russian military shipbuilder, diamond miner

Russian presidential aide Vladimir Medinsky, Russia’s lead negotiator in talks with Ukraine, said the two sides have made the most progress on the question of Ukraine’s “neutral status” during the negotiations, but that “nuances” remain around issues of security guarantees for Ukraine if it gives up joining NATO.

The “nuances are connected with what kind of security guarantees Ukraine gets in addition to ones it already has, in the case of renouncing joining the NATO bloc,” Medinsky told Russian media.

Medinsky said the two sides were “somewhere halfway” to meeting each other over the issue of Ukraine’s “demilitarization."

“As for demilitarisation, I would say it’s 50-50. The issues is I am now authorised to divulge any details of the negotiations and I will not do that, nor concrete figures, nor arguments of the sides, but in this part we are somewhere halfway,” he said.

At a massive concert in Moscow on Friday in support of Russia’s invasion of Ukraine, Russian President Vladimir Putin called the main goal of the military special operation to stop the genocide of the population of Donbass -- a false claim Putin has been spreading.

“It is precisely to save people from this suffering, from this genocide that is the main, main reason, motive and goal of the military operation that we launched in the Donbass and Ukraine,” Putin told the packed crowd in the city’s main stadium.

The concert was timed to mark the eight-year anniversary of Russia’s annexation of Crimea from Ukraine.

Russia's Foreign Minister Sergei Lavrov said Friday that any foreign supplies to Ukraine containing military equipment will be considered "legitimate targets" for Russian strikes.

"We clearly said that any cargo moving into the Ukrainian territory which we would believe is carrying weapons would be fair game. This is clear because we are implementing the operation the goal of which is to remove any threat to the Russian Federation coming from the Ukrainian soil," Lavrov said in an English-language interview with the RT television channel.

The Kremlin says Russian President Vladimir Putin in a phone call with Germany’s leader Olaf Scholz accused Ukraine of “seeking to drag out” negotiations with Russia to end the war by putting forward “new unrealistic proposals."

Putin told Scholz Russia was “nonetheless ready to continue the search for a solution within the bounds of its well-known principled approaches,” the Kremlin said in a readout of the call.

It’s a negative sign for the ongoing talks with Ukraine that both sides have suggested have made some progress this week.
