This culminated in a Thursday phone call between Prime Minister Mario Draghi and Russian President Vladimir Putin, wherein the Italian leader is believed to have pressed Putin to order his military to unblock Black Sea ports.

A statement from the Kremlin following the call said "Vladimir Putin emphasizes that the Russian Federation is ready to make a significant contribution to overcoming the food crisis through the export of grain and fertilizer, subject to the lifting of politically motivated restrictions by the West."

Putin's office confirmed he spoke about "steps taken to ensure the safety of navigation, including the daily opening of humanitarian corridors for the exit of civilian ships from the ports of the Azov and the Black Sea, which is impeded by the Ukrainian side."

Draghi's office in turn described that "the call was dedicated to developments in Ukraine and efforts to find a common solution to the ongoing food crisis, as well as the severe repercussions for the world's poorest countries."

The United States and leaders of several European countries have blamed Russia for increasing world hunger and ratcheting food prices and lack of supply, which is impacting already struggling and poor countries the hardest. However, Putin said the accusations are "unfounded" - following Russian officials earlier blaming Ukraine's military for deploying thousands of sea mines around its ports.

As Bloomberg reviews, "Russian Deputy Foreign Minister Andrey Rudenko said this week the government in Kyiv is to blame for the halt to grain exports from Ukraine because it mined its ports. Ukraine denies that, says it is Moscow that is preventing ships from docking and accuses it of stealing grain stores from occupied regions." Further, "A White House spokesperson said Russia’s actions were increasing world hunger."

Late yesterday, the Russian government - after being accused of using the food supply as blackmail and a bargaining chip - announced its military will open up protected sea corridors for international shipping to pass through from seven Ukrainian ports that have thus far been militarized and blockaded.

It's yet to be confirmed the degree to which this has happened, and likely most shipping companies and vessels would still deem the situation and ports near frontline fighting areas to be unsafe, given also the presence of mines.
