The 5th edition of the east Conference and Border Protection Fair "BRENICE'22" was launched. Artur Soboń, the Secretary of State at the Ministry of Finance stressed during its opening, in fresh months - although it would be hard to believe it only a fewer years ago - Poland had to build a wall on the border and "spiking" another part of it.
