Eastern European countries reach agreement on transit of Ukrainian grain.

Poland has reached an agreement to restart transit of Ukrainian grains through its territory as of Friday, which had been halted due to tensions with Russia. The transit will be monitored and sealed. Meanwhile, Ukraine says the Black Sea grain deal is under threat of being halted, and Russia has warned the US against "subversive activity" in the country. The G7 has vowed a unified front against Russia's war of aggression in Ukraine, while Russia is breaking its promises to countries dependent on Ukraine grain, according to US Secretary of State Antony Blinken.
