Poland said it will no longer supply weapons to Ukraine amid a diplomatic dispute over Kyiv's grain exports.
The BBC reported that Poland summoned Ukraine's ambassador over comments made by President Volodymyr Zelensky at the United Nations after Poland, Hungary and Slovakia extended a ban on Ukrainian grain.
On September 15, the three countries announced their own restrictions on Ukrainian grain imports after the executive European Commission decided not to extend its ban on grain imports into Ukraine's five European neighbors. Poland's ban covers four cereals and meals from corn, wheat and rapeseed.
Zelensky said it was alarming how some of Ukraine's friends in Europe were playing out solidarity "in a political theater -- making a thriller from grain."
On September 18, Ukraine filed a complaint to the World Trade Organization (WTO) over measures taken by Poland, Slovakia and Hungary to continue imposing restrictions on Ukrainian grain imports.
Ukraine and Slovakia have since agreed to a grain license system that would be soon setup, and Zelensky has withdrawn the suit against Solvakia.
Polish Prime Minister Mateusz Morawiecki told the Polsat news TV channel that Poland was no longer transferring weapons to Ukraine, because Poland needed to arm itself with more modern weapons. Poland's military hardware has been depleted by about a third through transfers to Ukraine, said the BBC.
Morawiecki noted he was not impressed with the WTO complaint and that he would increase the number of banned products if Ukraine escalated the grain dispute.
The two countries are working toward a solution to meet both of their interests.
First grain ship leaves Ukraine's Black Sea port
In related news, the first big ship carrying grain from a Ukrainian Black Sea port has set sail since Russia quit a deal in July to allow exports, a Ukrainian deputy prime minister tweeted on September 22.
The Aroyat "left the port Chornomorsk after loading 17,600 metric tons of Ukrainian wheat for Egypt," Oleksandr Kubrakov said on the X social media app, formerly Twitter.
Reuters reported it was the second of two bulk carriers to leave the port this week using what Ukraine calls a new temporary humanitarian corridor.
