bō lán波兰yǔ与wū kè lán乌克兰kě néng可能zài再yù遇liáng shí粮食yùn shū运输nán tí难题
Ukraine is an important grain-exporting country, but its ports and transport facilities have been attacked during the war. Together with drought and restrictions in European markets, this has made it increasingly difficult to ship grain out by sea.
Poland is therefore considering allowing Ukrainian grain to pass through its territory on its way to markets outside Europe.
However, when transport was opened in the past, some grain did not leave Poland. Instead, it was sold locally, causing grain prices to fall and prompting protests by Polish farmers.
Later, Poland banned Ukrainian grain from entering its domestic market, which eased the conflict somewhat.
Now, the two countries are discussing the resumption of transit transport.
The Polish government says it will continue to protect its domestic market, but some farmers worry that the old problems will happen again.
If large amounts of grain remain in Poland again, new protests may occur, and tensions in relations between the two countries and in Poland's domestic politics may deepen.
How to ensure that grain only passes through Poland and does not enter the local market will be key to solving the problem.
