When China’s military lagged behind US, it pursued an ‘assassin’s mace’ tactic. Smart weaponry and AI are changing that
- China’s focus on versatility, such as autonomous vehicles and AI-equipped weapons, is in contrast to weapons designed for asymmetrical warfare
- ‘Right now they’re like little sprinklings of AI that are coming into different military systems’ on both Chinese and US sides, says research fellow

The term, which refers to a weapon from ancient Chinese folklore that targets an enemy’s fatal weakness, has been applied by Chinese state media to the “carrier killer” DF-21D anti-ship ballistic missile that debuted in 2015 and by American military analysts to describe sea mines more than a decade ago.
It is a war concept not confined to China, having been deployed to target or exploit a bigger opponent’s weakness throughout history and across the world.
But the concept of individual and specific weapons for use in asymmetrical warfare – in which one side is perceived to be far stronger than the other – may have fallen out of favour in Beijing, particularly since the Chinese military has developed more sophisticated mechanisms and logistics and in an era of smart armaments.
The United States is also paying attention to the shift in focus. US officials say their country must harness the power of American industry to compete against Beijing in these general-purpose, cutting-edge military technologies.
