In 1931 Japan invaded Manchuria. To cover up their invasion, the Japanese imposed a new "puppet" government (a government controlled by them) that was meant to approve their presence in Manchuria. The name of Manchuria changed to Manchukuo and therefore so did the name of the government. The League of Nations sent a commission to investigate whether or not the Manchurians really wanted the Japanese there called the Lytton Commission. They determined that, in fact, the Japanese were not welcome in Manchuria. This basically eventually lead to the Japanese withdrawing from the League of Nations.

Strictly speaking, it is only parts of the Great Wall of China which are Heritage-listed. These sections have been given world heritage status because they are testament to the remarkable building programs undertaken by the ancient Chinese. They are a symbol of another era, and one which will not be repeated. Heritage listing helps protect such significant and ancient symbols, which have already been subject to vandalism through the years.
Contrary to popular belief, the Wall is not heritage-listed because it is the "only man-made structure visible from space". This is, in fact, a myth - refer to the NASA link below.
