The global COVID-19 pandemic is unprecedented in scale and scope. The COVID-19 vaccines have not only become an indispensable weapon in the fight against the pandemic but also served as a sign of the technological and scientific prestige of the countries that developed them. While the term "vaccine diplomacy" is not new, it may have become much more relevant in times of global pandemic. The aim of this research is to analyze the vaccine diplomacy of China, the EU, and Russia towards Serbia during the global COVID-19 pandemic. At the same time, the study also presents Serbia's efforts to engage in its own vaccine diplomacy at the global level. The novelty of this research can be seen in a comparative analysis of the efforts of the "vaccine diplomacy" of the EU, China, and Russia towards Serbia. In addition, this research also presents the results of the survey data on Serbian citizens and their perceptions of foreign aid received during the pandemic. It can be concluded that the Chinese and Russian medical aid to Serbia were very well received by the Serbian government, government-aligned media, and the Serbian public. Concerning the aid of the European Union, it was neither significantly advertised by the media, nor was the Serbian public perception significantly changed in the favour of the EU. At the same time, the Serbian government engaged in vaccine diplomacy of its own, to strengthen the ties with Yugoslavia's former allies from the Non-Alignment Movement.

The goal of this research consists in determination of impact of the Progress Party (Norway) and the Danish People's Party upon the policy of their national governments with regards to Russia. The Progress Party used to be member of the Norwegian government coalition from 2013 to 2020, while the Danish People's Party supported the Danish coalition governments from 2015 to 2019. The analysis of the origin, ideologies, political agenda, and policy of the parties give a more accurate explanation on their position towards Russia, as well as defines the level of their political willpower in influencing the government policy thereof. Research methodology is comprised of content analysis used in examination of the official documents of the Progress Party and the Danish People's Party, comparative analysis used in considering political programs of both parties, as well as various election results and other corresponding data. The conclusion is made that both parties have considerable impact upon the state policy of their countries with regards to the Russian Federation. Moreover, both of them demonstrated no political interest in making Russia the key vector in their foreign policy programs. Being neither of Russophile nor Russophobic nature, their presence in the government did not become the reason for deterioration or improvement of relations with Russia.

Modern battlefields around the globe demonstrated the employment of the next generation of weapons which are colloquially designated as "killer robots", or Lethal Autonomous Weapon Systems (LAWS). Although LAWS, for now, are always under the supervision of the human operator, the technological advancements in Artificial Intelligence allow for such weapon systems to achieve a significant degree of autonomy, including the autonomy over the decision-making process of utilizing the lethal force against the human targets. Due to the lack of global regulation for the research, production, and deployment of LAWS, they are seeing more and more employment in contemporary battlefields, from Libya, Syria, Yemen, and Nagorno-Karabakh to Ukraine. The goals of this article are to understand the limitations of the AI that can be employed in LAWS; to present an overview of the current LAWS via the available public data; to assess the state of the regulations of the LAWS, by employing comparative analysis of strategies and positions towards LAWS from the side of the EU, the USA, China, Russia, and India. The results of this research demonstrate that barring the EU which is in the process of adopting a regulation that will enforce a total ban on the LAWS, the other major powers express a balanced approach towards this issue by reserving rights to develop and employ LAWS for the goals of their national security, per the Article 36 of the 1977 Additional Protocol I to the 1949 Geneva Conventions.
