The sane approach to deal with the legitimate concern of undercutting prices would be to set a minimum price instead. That would result in European farmers not unnecessarily getting dragged into an undercutting war and Ukrainian farmers would get more money.

Uncool poland. Somehow poland can still undercut prices in baltic states, maybe we should ban em too

This is a really frustrating story:

Earlier in July, Polish farmers called for a ban on frozen raspberries import from Ukraine, saying that their influx could destabilize the market prices in the country.

This already after:

On May 2, the European Commission banned the sale of Ukrainian wheat, maize, rapeseed, and sunflower seed in Bulgaria, Hungary, Poland, Romania, and Slovakia until June 5 in a bid to “alleviate logistical bottlenecks,” but allowed their circulation in other European markets. The ban was later extended until September 15.

Disclaimer: I’m not an economist, so I don’t know how much this affects export prices.
