The Organisation for Economic Co-operation and Development (OECD) is yet another institution that has appreciated Poland's economic policy, PM Mateusz Morawiecki said on Twitter on Wednesday. In its biannual forecast published on Tuesday, the OECD has raised Poland's GDP growth forecast to 4.2 percent from 4.0 percent in 2019 and to 3.5 percent from 3.3 percent in 2020.
