The US has done tests with eLoran as well. The receivers are quite expensive and the signal isn't permanent yet, so it's more of a lab thing right now. Also experiments with BPS (Broadcast Positioning System) using high power TV transmitters to distribute time and position in urban areas (very hard to overpower that signal).
The Wikipedia page says that China has deployed an eLoran network but I can't tell if used for navigation or just high-precision timing.
