What’s at stake in the upcoming Erdogan-Putin meeting?

Turkish President Recep Tayyip Erdogan is scheduled to meet Vladimir Putin on Monday, hoping to persuade the Russian leader to rejoin the Black Sea grain deal that Moscow broke off from in July.
The meeting, to take place in Sochi on Russia’s southern coast, comes after weeks of speculation about when and where the two leaders might meet. Erdogan previously said Putin would travel to Turkey in August.
