Some quick Googling implies China has satellites capable of tracking shipping via radar from geostationary orbit. I'm not really convinced that aircraft carriers can hide these days?

Those satellites KNOW where the freighters are going, and check in every day on progress. They aren't looking for something that's intentionally sailing in an unpredictable direction (with no radio emissions in wartime).
