The Polish foreign ministry said in a statement on Sunday that the Pole "had been arbitrarily detained in Venezuela for a year."
The ministry also noted "the readiness declared by the current authorities in Caracas to develop relations with the European Union and the United States."
It said Poland "is ready to share its historical experience in the field of national reconciliation and to support Venezuelans in achieving a negotiated, democratic, inclusive, and peaceful resolution of the crisis."
Venezuelan human rights organisation Foro Penal said that between January 8 and 17, the new authorities had freed 139 political prisoners from detention facilities following the capture of President Nicolás Maduro by American forces.
Foro Penal, along with other non-governmental organisations, has been campaigning for the release of political prisoners in Venezuela.
The organisation had previously said that more than 800 such prisoners were being held in Venezuelan detention facilities, including the Polish citizen, who also held a Ukrainian passport.
On the morning of January 3, American forces carried out a series of strikes in Venezuela aimed at apprehending Maduro.
He was transported with his wife to New York, where he is facing trial on charges including drug-related crimes and terrorism.
According to Foro Penal, more than 18,600 people were detained across Venezuela for political reasons after Maduro came to power in 2013.
