ODESA, Ukraine (AP) — President Volodymyr Zelenskyy visited one of Ukraine’s main Black Sea ports Friday, a week after a deal was struck with Russia, Turkey and the United Nations to create safe corridors for ships to export grains that have been tra

His visit to a port in the Odesa region comes as workers were seen preparing terminals for grain exports, which are relied on by millions of impoverished people worldwide facing hunger.

“The first vessel, the first ship is being loaded since the beginning of the war,” Zelenskyy said.

He said the export of grain will begin with the departure of several ships that were loaded but could not depart the Ukrainian ports after the Russian invasion.

“Our side is fully prepared. We sent all the signals to our partners — the U.N. and Turkey, and our military guarantees the security situation,” he said, adding “it is important for us that Ukraine remains the guarantor of global food security."

The visits to the ports are part of a broader push by Ukraine to show the world they are nearly ready to export millions of tons of grains to the world again after last week’s breakthrough agreement

pped in the country since the war began five months ago.

The complexities of the agreement and concerns about the safety of shipping crews has set the deal off to a slow, cautious start. It's been a week since it was signed, and no grains have yet left ports. But the sides are facing a ticking clock — the deal is only good for 120 days.
