Speaking a day after talks with his Ukrainian counterpart, Mykola Solskyi, in Lviv, Nagy said on news channel M1 that logistics infrastructure on both sides of the border need to be upgraded, adding that Hungary would turn to the European Union for support to expand transshipment capacity.

With Black Sea ports blocked, through which 90pc of Ukraine's grain exports normally pass, some 22 million tonnes of grain is stuck in storage in Ukraine, leaving farmers little room to put this year's harvest and creating a disincentive for planting next year's crop, he said. He noted that Ukraine grows 9% of the world's grain and warned that the situation could cause a global food crisis.

Nagy said decisions on priorities regarding transshipment capacity must be taken, too. Grain is on the agenda now, but other goods also need to reach Europe, such as artificial fertilizer, commodities, and feedstock, he added.

At his talks in Lviv, Nagy said the sides looked for operative solutions to expand logistics capacity on the border through joint planning and coordination. In addition to short-term measures, steps for the long term must also be taken as Ukraine develops closer economic ties with the European Union, he added.
