This story makes no sense. (E)
If anyone never needed to open an illegal bank account, using a false foreign resident's card somehow received thanks to his old University of Tokyo ID, this in order to receive money transfers of consulting fees from Japanese companies, then First Secretary Li Chunguang of the Embassy of the People's Republic of China was that person.
Li was as well-connected as any Chinese could conceivably be, having studied both at the prestigious Matsushita Institute of Government and Management -- the finishing school of both Prime Minister Noda Yoshihiko and Foreign Minister Gemba Koi'ichiro-- and at the University of Tokyo's Institute of Oriental Culture, presided over during the years Li was there by the extremely influential Tanaka Akihiko, now Todai's Vice President.
Li should have never been in need of money, at least not in performance of his duties. In addition to his diplomatic salary, he was secretly a member of the General Staff of the People's Liberation Army. With his fluent Japanese and his contacts in business, government and politics, it is inconceivable that China's Ministry of Foreign Affairs, Chinese security agencies and/or the PLA would not have a limitless and quite legal ATM account for Li to draw upon to pay for information, when he needed to do so.
So I think Channel Sakura, which has an old Okazaki Institute (!) seminar video showing Li's face, name and affiliation (Your tube - J) and the major news outlets are mistaken in claiming that Li used the money he accepted as consulting fees for spying purposes. It just does not stand to reason that anyone in the Government of China would sign off on such clumsy method of buying information.
Then again, it is impossible to understand how someone as valuable as Li would ever stoop so low as to be shilling for what amounted to pocket change.
Like I said, this story makes no sense.
The only person who can explain it is Li, who made it out of the country on May 23, just ahead (?!?) of Japanese authorities ready to detain and expel him for violations of the Vienna Convention prohibiting serving diplomats from conducting business in the countries in which they do their service.
My guess is that no one will be seeing much of the handsome and worldly Mr. Li for quite some time.
