Hidden Reach

Hidden Reach is a CSIS special initiative that shines light on under-appreciated sources of China's far-reaching influence through open-source data and satellite imagery.

China is increasingly a global power. Its overseas interests are vast and complex, spanning every region of the world. In many places, Beijing is leveraging new sources of strength to assert its influence. Yet key elements of its far-reaching footprint remain poorly understood.

Using satellite imagery and open-source data analysis, Hidden Reach illuminates new details in the story of China’s expanding international influence, focusing on areas left out in Beijing’s official narrative.

Presented through interactive digital reports and other multimedia content, our work seeks to cut through noise and jargon to help policymakers, academics, and the interested public gain a nuanced understanding of China’s global rise.
