To be fair, that instance was a crash of 50 kg of U-235, if which only 0.5 kg was recovered. Apparently the controlling international instrument is the Space Liability Convention (1972) [0]. Ratified by the US, Russia, China, India, Europe, et al. The only catch is you have to get your government to initiate a claim against the responsible government. E.g. Ivory Coast bringing a claim against China. [0] https://en.m.wikipedia.org/wiki/Space_Liability_Convention https://en.m.wikipedia.org/wiki/Space_Liability_Convention
