Extreme ultraviolet lithography (EUV) is a groundbreaking technology used to create the world's fastest microchips, essential for powering advanced AI models. This technology, once thought impossible, involves using a powerful laser to create extreme ultraviolet light that etches circuits onto silicon wafers. The Dutch company ASML is the only firm capable of producing these advanced etching machines. The development of EUV was nurtured in U.S. nuclear labs and tech companies, and the U.S. is keen to prevent China from accessing this technology.

Despite Western sanctions, Russia has been able to import an increasing number of Western microchips and semiconductors through intermediary countries like China, according to trade data and analysis. These microchips and semiconductors play a crucial role in powering Russia's military equipment, including drones, missiles, and armored vehicles. Many of these components are subject to export controls, but convoluted trade routes and the classification of certain technologies as dual-use items have allowed them to enter Russia. The ubiquity and wide-reaching applications of these technologies make them difficult to police, and sanctions on Russia are limited to Ukraine's Western allies. China is the largest exporter of microchips to Russia, accounting for over 87% of total Russian semiconductor imports in Q4 2022. Calls have been made for more countries to join sanctions or impose secondary sanctions on entities facilitating Russia's military strength.
