In recent months, the three Belarus-bordering countries have experienced mounting entry attempts by Middle Eastern migrants from the Belarusian side, which they say are facilitated by Belarus in a bid to destabilise the EU.
"Together with Lithuania and Latvia, we have full support regarding defence measures against this hybrid war and the migration wave instigated by the (Belarusian - PAP) regime," Mateusz Morawiecki told the summit.
Referring to Poland's introduction of emergency laws in areas close to its border with Belarus, Morawiecki said the move was necessary as the entry attempts from Belarus were "a mechanism aimed at wreaking chaos in the EU."
"It is perfectly evident that the emergency laws were necessary, that all these attempts to draw migrants... are aimed at bringing chaos to the EU... This is why Poland, as well as Lithuania and Latvia, have absolute support in this respect," Morawiecki said.
Morawiecki also said that in protecting its border to Belarus, Poland was also protecting the outer frontier of the EU. (PAP)
