Russia blockaded 20 million tonnes of Ukrainian grain in 2022.

Omissions

• The 20 million tonne figure is an estimate that varied over the course of 2022 (some official and press accounts cited 20–22 million tonnes trapped, depending on the reference date and whether oilseeds were included).
• The claim's broader assertion that global grain stockpiles are currently larger than in 2022 is not addressed by the sources verifying the 20 million tonne figure and would require separate verification (e.g. USDA/IGC/FAO stock-to-use data).
• The 20 million tonnes were blocked because ports were closed by the Russian naval blockade, not because Russia physically seized that quantity of grain; the phrasing is a shorthand widely used in official communications.
