The Chinese might disagree
CE-2 was on a secondary mission after being parked at earth/sun L2, so yes landing wasn't part of the objective, merely a rendezvous exercise and seemingly successful.
The Chinese have had ambitious space plans even talk of crashing into a asteroid to divert its orbit and would like to be in the league of Japan's landing on Hayabusa along with Nasa's Near landing on Eros. With this encounter of Toutatis Beijing will surely to build on its confidence.
Years away, oh yeah, many and it will probably be other objects.
