There is the global trend among politicians all over the world, to make promises through social media to reach a larger audience. While recently Twitter, Facebook and Telegram were mainly used for entertainment and informal communication, now they are actively applied by state authorities for professional purposes. Almost all politicians of democratic States open-handedly promise to provide economic assistance to the developing States, supply military equipment to Ukraine, impose sanctions on Russia and limit
greenhouse gasses emissions. Nevertheless, the majority of these promises remain unperformed.
The question that arises regarding this situation is whether the doctrine of unilateral declaration applies to the promises of State officials made through the social media platforms and how those rules could be implemented. The aim of this work is to provide an answer to that question.
