China claims that they have completed the "world's highest-resolution 3D map of the moon," which will serve Chinese astronauts to reach the Moon in 2020. Of course, one thing is claiming that, the other is being reality.
The Chinese said the resolution of their 3D map—made with their Chang'e-1 probe, sent in October 2007—is 500 meters. Obviously, there has to be an error somewhere, because JAXA's own 3D map's resolution is 10 meters. Not to talk about NASA's LRO, which is 3 meters. In all fairness, the NASA map is not completed yet, but the Japanese one is.
