The power competition between the major powers of the world has always been dependent on the strategic security landscape. Over the years, military operations and warfare have evolved with the development of new weapons, equipment, and technologies. During the 20th century, the world witnessed a transformation from conventional strategic competition to unconventional strategic competition with the advent of nuclear weapons. The genesis of the 21st century marked another revolution in military affairs when electronic warfare was modernized and cyber warfare came into the spotlight. In the current century, new poles of powers have emerged whereby Beijing and Washington started competing at all levels and in all domains. Shortly after the incorporation of digital, electronic, and cyber equipment and techniques by militaries around the world, cyberspace became militarized and emerged as the fifth battlefield. The U.S. armed forces and the Chinese PLA both rely heavily on cyberspace when it comes to their communication, operations, and planning. Cyber campaigns launched by Washington and Beijing on various targets accounted for a cyber arms race and continuous cyberspace strategic competition between the two countries.
