Ukraine, a major global grain exporter, has been seriously hindered in selling grain. Poland, which supports the country in the conflict, has offered it its own grain export channels.
Henryk Kowalczyk told a sitting of provincial governors in the southern city of Lublin that aiding Ukraine's grain exports was a major challenge, especially when it came to transporting it from the country.
"We feel the need to help Ukraine... but we are also aware of the various hazards involved," Kowalczyk said.
He added that since last Monday Poland has introduced stringent checks on grain coming from Ukraine to eliminate so-called technical grain, i.e. grain not fit for human consumption, from the transports. (PAP)
