Abstract: This paper examines the fragmentation of global science and the changing role of the BRICS countries in international research collaboration under geopolitical pressure. Using bibliometric analysis of more than 688,000 semiconductor-related publications indexed in the Web of Science Core Collection (1965–2025), the study traces how the imposition of sanctions since 2022 has transformed global co-authorship networks. The findings demonstrate a structural shift from a previously integrated international scientific system toward a constellation of regional clusters. China has consolidated its position as the central node of the global publication network, assuming integrative functions once held by the United States and the European Union. India has increased its connectivity, strengthening ties within BRICS and with the Global South. Russia’s role has markedly declined following the suspension of collaboration with Western institutions, accompanied by a drop in joint publications. At the same time, Saudi Arabia and Egypt have emerged as new peripheral hubs, reflecting a reallocation of scientific collaboration toward countries not affected by sanction regimes. Network-metric analysis (degree, betweenness, closeness, and eigenvector centrality) confirms the polarization of the international research system. Sanctions have weakened traditional nodes while fostering new centers of influence within BRICS and the Global South. The paper concludes that sanctions have accelerated the regionalization of global science, transforming the semiconductor research landscape from a unified global network into multiple interconnected regional systems, each with its own core and sphere of influence.

Abstract: The approach of development economics has been rarely used in the studies on the BRICS research agenda. This article is an attempt to fill this gap. According to development economics, the appearance of the BRICS association is fully justifiable, because large emerging economies have much in common. Russia is the most advanced country among the BRICS, even though some years ago it fell into the group of laggards in terms of economic growth, together with Brazil and South Africa. It may be partly explained by those countries’ adherence to neoclassical recipes of economic policy. It is believed, however, that national economic interests of all the five countries could be more effectively served by a combination of further pro-market reforms with public interventions to correct the inevitable market failures. That is why, for the Russian comparative advantages to be fully realized, the country should rely not so much on trade liberalization as on coordination among the BRICS governments in their actions aimed at trade and investment promotion.
