Mykhailo Podoliak, an adviser to the chief of the president's office and a member of the negotiating team with Russia, summed up the talks in Istanbul.
He wrote on Twitter that one of the negotiating points was legal guarantees, which are analogous to NATO's fifth article and provide a new security framework.
"Istanbul summary. Legal guarantees that provide a new security framework for Ukraine (similar to NATO's fifth article). Return of the issue of Crimea to the negotiating agenda. Proof of Ukrainian statehood. Start of revision of global security principles and the role of institutions," he added.
Стамбульський підсумок. Юридичні гарантії, які забезпечують новий контур безпеки 🇺🇦 (аналог п'ятої статті НАТО). Повернення проблематики Криму у переговорний порядок денний. Доказ спроможності 🇺🇦 державності. Початок перегляду глобальних принципів безпеки та ролі інституцій.

At the same time, Putin's spokesman Dmitry Peskov said today that Crimea will not be the subject of negotiations with Ukraine, because Russia considers the Ukrainian land seized in 2014 its own.
Ukraine, in turn, insists that the status of Crimea and Sevastopol should be resolved with Russia in bilateral negotiations no longer than fifteen years.
The Ukrainian delegation held talks with Russia yesterday. After that, the Russians went home and representatives of Ukraine continued talks with Turkish officials.
