Experts expect negotiations at the gathering to be long, with some predicting they will be acrimonious.
Polish Prime Minister Mateusz Morawiecki said earlier this month that his country and 16 other European Union members strongly oppose plans to restrict the bloc’s cohesion and agricultural policies.
And in an opinion piece published in Britain’s Financial Times on Wednesday, Morawiecki argued that cuts would weaken the bloc.
"It is clear that lowering spending would mean weakening the European project," Morawiecki wrote.
He added that the next EU budget was one of the biggest and most contentious issues faced by the bloc.
Morawiecki has previously warned that the European Commission's proposal on the 2021-2027 budget was “insufficient” and “not ambitious enough,” Poland's PAP news agency has reported.
Meanwhile, in a special article for Tuesday’s edition of German daily Die Welt, Morawiecki said he wanted Europe to be a “global player,” adding that for this the EU needed a “good budget.”
