This paper highlighted the use of cyberspace as a conflict zone by the US and China, focusing on competition in various technological spheres, including cyberespionage, military technology, and Artificial Intelligence (AI). The main purpose of this study was to depict how great powers manipulate the cyber domain for their high political objectives through US-China rivalry. The research has been carried out mainly via literature review, discourse analysis, and relevant statistics. Consistent with previous literature and global public perception, the outcome has shown that both states are using cyberspace as a new domain for completion in trade, technology, and military purposes. Cyberespionage, the militarization of cyberspace, and AI have been the main conflict areas between these two global competitors in the last decade.
