Poland plans to recruit around 35,000 volunteers for a militia within the next few years, a government official said Thursday.

The voluntary members will receive a monthly payment of 500 zloty (127 dollars), Grzegorz Kwasniak, a Foreign Ministry official responsible for paramilitary groups, said at a defence trade fair in Ostroda, Poland.

At an upcoming summit in Warsaw on July 8-9, NATO is expected to decide on the deployment of battalions to Poland and the Baltic states, a move that would likely further antagonize Russia, which has previously said that the alliance‘s eastward expansion threatens its national security.

Relations between NATO and Moscow have reached their worst point since the Cold War over Russia‘s annexation of the Crimean peninsula and its support for separatists in eastern Ukraine. Both sides have been flexing their military muscles in eastern Europe ever since.

A small group of paramilitary organizations will take part in NATO training exercises named Anaconda in Poland in June, the Polish Defence Ministry said.
