Espacio Lejano Station, a Chinese deep-space ground station in Neuquen, Argentina, with a 35-meter antenna.
The engine reads it as effectively a Chinese sovereign enclave inside Argentina with almost no local oversight.
It's run by the PLA Strategic Support Force (China's military, not a civilian agency) on a 50-year tax-free lease from 2017, Argentina cannot interfere with or interrupt its operations, and while it's officially for lunar tracking it also has inherent capability for space surveillance, intercepting satellite communications, and supporting Chinese military operations globally.
It matters as a foreign military installation embedded in another country's territory with near-zero accountability.
