Not too many people are aware that China approved of National Mobilization Law on February 26, 2010, which we find quite similar to Old Imperial Japan's National Mobilization Law enacted in 1938 in preparation for the total war by the first Konoe Cabinet.
This law went into effect on July 1, 2010. One implication we must focus on is that Chinese nationals wherever they are now could turn into operatives who may carry out whatever they are ordered to do by Beijing government.
The ruling party Democratic Party of Japan has so far created the environment which allows the Chinese nationals to easily visit Japan by easing visa restrictions, etc.
It is said that every week about 500 Chinese nationals (some Chinese with false documents) come to Japan not as tourists but to settle down here. Some of them apply for the governmental aid similar to U.S. temporary assistance for needy families.
Some say that those Chinese nationals not only in Japan but spreading all over the world may turn out to become Peoples' Liberation Army soldiers whenever Beijing orders them to be in accordance with the National Mobilization Law.
