Separately, Russia rejected a parallel proposal from Türkiye for a Black Sea moratorium. Zakharova said Moscow had not received any formal Turkish proposal through official channels, despite Ankara's efforts to mediate .

Reasons for Moscow's Rejection

Russia's refusal rested on four main arguments:

• Military rationale: Russia views any truce as a one-sided pause that would let Ukraine regroup and rearm its forces, not as a genuine step toward peace . Zakharova explicitly stated that a limited ceasefire would only give Kyiv "breathing space" .
• Rejection of the old framework: Moscow said it sees no point in returning to the 2022–2023 Black Sea Grain Initiative model, which it has long criticized as failing to deliver on promised concessions for Russian grain and fertilizer exports . Zakharova called that arrangement a "unilateral scheme" that made "no sense" to revive .
• Blame-shifting: Russia insists the escalation was caused by Ukrainian "terrorist" attacks on Russian ships and ports, making a mutual halt unacceptable from its perspective . Zakharova accused Ukraine of a "deliberate policy aimed at destabilizing civilian shipping" .
• No formal proposal received: Ahead of the public rejection, Deputy Foreign Minister Alexander Grushko claimed Moscow had not received any official ceasefire offer from Ukraine . Zakharova similarly said Russia had not received a "formalized Turkish appeal" through official channels .

How the Mutual Strikes Threaten Global Food Supplies

Both sides are now hitting each other's grain export infrastructure simultaneously, creating a dual disruption that experts warn could trigger a global food price spike.

Russia's Strikes on Ukraine

A Russian campaign of missile and drone attacks has targeted cargo vessels and port infrastructure around Odesa, effectively halting nearly all shipping in and out of Ukraine's main port hub . No vessel entered Odesa-region ports for two weeks in late July . Ukraine's grain export forecast for the 2026/27 season was cut by up to 12%, to 38–40 million tons . The country's monthly grain shipping capacity has fallen by roughly a third .

Ukraine's Strikes on Russia

Ukrainian drone strikes on August 12–13 severely damaged two of Russia's largest grain terminals at Novorossiysk, rendering grain shipments from Russia's key Black Sea export port temporarily impossible . Russia is the world's largest wheat exporter, and most of those exports are shipped through Novorossiysk . Industry sources told Reuters that a loading gallery at one terminal collapsed and several silos were damaged .

The Combined Effect

Russia and Ukraine together account for roughly 30% of global wheat exports . With both countries' export capacity degraded simultaneously, global grain prices have already risen sharply . The UN World Food Programme has warned that continued disruptions could trigger a sudden jump in food costs, hitting import-dependent countries in Africa, the Middle East, and South Asia hardest .

Ukraine recorded 35 attacks on vessels in port and 22 at sea in July, along with 67 strikes on port facilities, according to the country's Infrastructure Ministry . Analysts now describe the Black Sea as a "new strategic trade chokepoint" that threatens both grain and oil supply chains .

What Comes Next

With the ceasefire proposal rejected and both sides intensifying attacks on each other's economic infrastructure, the immediate outlook for Black Sea grain exports remains precarious. Ukraine's agriculture minister has said that alternative export routes can cover only about 50% of the volumes normally handled by Black Sea ports, and they will not reach required capacity until at least the end of August . Meanwhile, Russia's main grain lobby group has warned that continued Ukrainian drone attacks could shut down Black Sea grain exports entirely in the near future, pushing up prices and "causing hunger in Africa and the Middle East" .
