CHINA WATCHChina’s Militarization of Meteorological Balloons
Beijing’s spy balloon is a clear example of an emerging technology developed for military and intelligence operations but that crucially evolved out of civilian and scientific programs. China’s balloon-technology programs contain sober lessons about Beijing’s incremental acquisition of foreign intellectual property and its technology partnerships with Western research institutions.
China’s Ministry of Foreign Affairs was quick to claim that a spy balloon breaching US territorial airspace and flying close enough to military sites to monitor them was ‘a civilian airship used for research, mainly meteorological, purposes’ that had accidentally wandered off course. Pentagon officials and the US intelligence community dismissed that claim and linked the balloon to a ‘vast surveillance program’ run by the People’s Liberation Army Air Force, partly operating out of Hainan province on China’s south coast.
Beijing’s spy balloon is a clear example of an emerging technology developed for military and intelligence operations but that crucially evolved out of civilian and scientific programs. One company that is a strong candidate for contributing to the development of the balloon—and certainly works on similar technology that it supplies to the PLA—is a Shenzhen-based metamaterials company, Kuang-Chi, which has also been sanctioned by the US government for human rights abuses in China.
Open-source documents and media reports about China’s balloon-technology programs contain sober lessons about Beijing’s incremental acquisition of foreign intellectual property and its technology partnerships with Western research institutions. This in turn highlights the difficulty in assessing dual-use technologies and serves as a reminder that Western countries need to review their scientific and commercial collaborations to ensure that those arrangements don’t allow an adversary to deploy those capabilities against their interests.
To analyze the value that China’s military leadership attaches to balloons and the near-space region (between 20 and 100 kilometers above the earth’s surface), it’s important to understand Beijing’s strategic intent and the resources it has allocated to such capabilities. Various Chinese government documents indicate that meteorological balloons, and other stratospheric airships, are important to the PLA’s aerospace strategy.
China’s 14th Five-Year Plan for National Economic and Social Development and Long-Range Objectives for 2035 lists aerospace technology (空天科技) as a frontier area of research where Beijing is deepening military–civilian collaboration to improve China’s military and economic strength and ensure the nation achieves its ‘centennial military building goal’ by 2027. As an example, a project titled ‘The high-resolution earth observation system’ (中国高分辨率对地观测系统), which includes near-space systems, is one of China’s 16 primary science and technology projects. This highlights the strategic significance of unmanned aerial vessels for Beijing.
