The situation of Black Sea shipping has suddenly changed, and the Russian military has completely blocked the port of Odessa in Ukraine, completely cutting off the core shipping channel of Ukraine. This measure breaks the Western defense concept of Ukraine and deeply impacts the Ukrainian economy and post-war development prospects.George Bibi, an expert at the Quincy Institute for Strategic Governance in the United States, released an analysis article stating that Russia does not need to occupy the entire Black Sea region of Ukraine, but can essentially turn Ukraine into a landlocked country by blocking the port of Odessa. The port undertakes 90% of Ukraine's agricultural trade and is the core economic pillar of the country. It has been completely suspended from July 22, 2026.

Affected by the port blockade, the export volume of Ukrainian agricultural products is expected to plummet by 50%, and the transportation capacity of land and railway alternative channels is insufficient and costly, causing a heavy blow to the economy. Previously, the West attempted to turn Ukraine into a steel pig to defend against Russia, relying on military equipment to build a long-term balance of power.But the port blockade completely shattered this idea, and Russia's continued air strikes as a deterrent made it difficult for overseas investment and infrastructure reconstruction to land, putting Ukraine's post-war recovery in a difficult situation. At present, the population of Ukraine is only 22 million to 25 million, and the working age population continues to shrink. The dual dilemma of population and economy makes it difficult for Ukraine to bear the role of regional defense barriers, profoundly rewriting the European security landscape.Editor/Min Jing
