edit: A simple web search in Chinese may turn up something, but I don't know anyone personally who is both both fluent and interested in space exploration. This is a pretty cool orbit - there must be something somewhere!
I tried to find Chang'e-2 in the JPL Horizons database but couldn't find it. Since I had previously gotten data for Rosetta and Hayabusa just by typing their names, I didn't realize that those were unusual cases and it's pretty much only NASA missions there.
Chang'e-2 has had quite an interesting orbit. From Earth to Lunar orbit, then the first ever transfer directly from lunar orbit to Earth-Sun L2, then a flyby (within 3.2 km) of 4179, and now... where is it?
Is there any kind of numerical data available so I can reconstruct this in 3D?
I'd like to follow the orbit. Here are some updates from here:
Mission status:
As of 2015, the Chang'e-2 has reached a distance of over 100 million km from Earth.
In June 2014, the Chang'e-2 Probe is more than 90 million km away from the Earth, and is expected to fly back to a position 7 million km from the Earth in 2029.
On July 14, 2013, the Chang'e-2 Probe had reached a distance of 50 million km from Earth, marking a new height in the nation's deep space exploration...
