Chinese researchers have developed a compact, deep-sea device capable of severing even the most fortified underwater cables.
The development raises concerns that Beijing could target critical communication and power lines, especially in the event of a Chinese invasion of Taiwan.
The tool can slice armoured cables at depths of up to 4,000 metres (13,123 feet), which is twice the maximum operational range of existing subsea communication infrastructure, according to an academic paper seen by the South China Morning Post.
