The Washington Post: Chinese companies have sharply increased supplies of fiber optics and lithium-ion batteries to Russian drone manufacturers
During the summer of 2025, supplies of fiber optic cable and lithium-ion batteries, as well as other components for assembling drones from China, increased sharply, The Washington Post writes, citing Chinese customs data.
