Former Russian president Dmitry Medvedev declared on Saturday that Moscow will seek "revenge" for the Western sanctions, a day after the EU revealed a 13th set of sanctions against Russia.

The latest sanctions aim at 500 targets, including the Mir credit card system, which was established by Russia to avoid depending on US-based networks or businesses.

"The reason (behind the sanctions) is clear: the worse it is for Russian citizens, the better it is for the Western world," Medvedev said on social media, adding: "We all just need to remember this and take revenge on them wherever possible. They are our enemies."

He urged Russians to "create difficulties in the economy for (the West) and foment public unhappiness towards the incompetent policies of Western authorities."

He also stated that Russia should "carry out other activities on their territory that cannot be discussed in public".

It is worth noting that the new package of sanctions against Russia coincides with the second anniversary of the war in Ukraine.

This set of sanctions is aimed at restricting Russia's military might, with a total of 194 individual designations, including 106 individuals - including the Russian Defense Minister - and 88 entities affected by the package. 

Over 140 companies and individuals from the Russian military-industrial complex, which manufacture missiles, drones, anti-aircraft missile systems, military vehicles, and high-tech components are targeted by the sanctions.

The US' Under Secretary of State for Political Affairs Victoria Nuland also announced two days ago that the US is preparing a new round of fresh sanctions against Russia, which, as per her words, promises to be "crushing".

The possibility exists that the sanctions could be linked to the recent death of the Russian opposition figure Alexei Navalny.
