WARSAW (Reuters) - Poland and Ukraine will resume negotiations early on Tuesday to try to reopen the transit of food and grains, the Polish agriculture minister told public radio station PR1.

The two countries held talks on Monday over bans by central eastern European countries seeking to shelter their farmers from the impact of an influx of cheaper Ukrainian grain.

Some Black Sea ports were blocked after Russia's invasion of Ukraine and large quantities of Ukrainian grain has been trapped in Central Europe because of logistical bottlenecks.

"We are talking with the EU as well as with Ukraine to find solutions. We want these products to go to Europe, but go deep into Europe," Agriculture Minister Robert Telus said.

"We talked yesterday, there were long talks. Today we are also sitting down for talks...These are typically technical talks to find a solution and let this transit go to Europe," he added.
