What did Turkey's mediation offer change in 2021?

What did it mean when Turkey offered to mediate between Ukraine and Russia on 29 November 2021? On that date, Turkey put itself forward as a go-between in the conflict between the two countries, which the reports of the time placed within the Russo-Ukrainian War.

The offer was a statement of intent, not a negotiated process. The reports of that day described no talks scheduled, no format agreed and no response from either side, so any assessment of its weight has to rest on the offer itself: a third country was willing to host or facilitate dialogue between the parties.

That in itself is worth noting for an international readership. A mediation offer signals that a conflict is regarded abroad as unresolved and in need of diplomacy. Turkey's proposal placed it among the states prepared to take on that role.

The offer also sat alongside domestic news in Ukraine. On 27 November 2021, a gas explosion was suspected in a five-storey residential building in Nova Odesa, in Mykolaiv region. Two flats were destroyed, three people died and three were injured. The two events were unrelated, but they marked the same weekend in the country's news.
