Poland announced the 'Schutzschild Ost' plan with a €2.3 billion investment to fortify its eastern border with Belarus, Russia, and Ukraine by 2028.

The government plans to restrict the movement of Russian diplomats due to suspicions of Moscow's involvement in cyberattacks and hybrid warfare against the EU, including spying and sabotage activities on Polish territory.

The $US2.5 billion Shield-East program aims to strengthen anti-drone surveillance and military defense along the eastern border with state-of-the-art technology such as defense towers, barriers, bunkers, and shelters.

The initiative is part of a broader effort to bolster NATO's eastern flank and protect the EU's eastern border, with funding from both the government and the EU.

Poland's actions come amidst deteriorating relations with Russia following Moscow's actions in Ukraine.

The government's security measures have political implications ahead of European Parliament elections and have received bipartisan support.

The move is seen as a significant step in enhancing regional security and sending a warning signal to Russia.
