"For the first time, the EU joins in the defence of Poles in Belarus," Dworczyk wrote in a Twitter post on Friday. "Every repressed Pole on the other side of our eastern border can count on Poland's support."
Belarusian authorities have arrested Andzelika Borys, head of a Polish diaspora organisation, and three senior members of the organisation, while other Polish activists have also been persecuted. Borys was detained for 15 days for "organising an illegal mass event," a traditional annual fair for the Polish diaspora.
Apart from the EU, Poland's protest has also received support from the US and Lithuania, the Council of Europe, the UN and other international organisations.
On Friday, Polish President Andrzej Duda spoke with Council of Europe Secretary General Marija Pejcinovic Buric, who assured him that the Council of Europe's Committee of Ministers would debate the issue next week.
Also on Friday, Duda met with representatives of the Belarusian diaspora in Poland. Wojciech Kolarski, a presidential aide, said there were no negative emotions between Poles and Belarusians.
Duda also discussed the situation of the Polish minority in Belarus with leaders from the Organization for Security and Co-operation in Europe and the United Nations.
Poland has also brought the matter up in NATO. (PAP)
