One of Ukraine's staunchest allies, Poland, has announced it will no longer supply weapons to the country as a diplomatic dispute over grain escalates.

From your source:
Poland has already sent Ukraine 320 Soviet-era tanks and 14 MiG-29 fighter jets and has little more to offer.
and
Arms exports to Ukraine will not stop completely as Polish manufacturer PGZ is due to send about 60 Krab artillery weapons in the coming months.
So not quite the fit of pique it seems from the headline. Hopefully as the "modern weapons" come on stream in Poland further stocks of ex soviet gear will be released. The question then is the timeframe.
