While sending a long-term message that we abandon democracies in order to gain those same short-term benefits. Bad idea…

Moreover, memories run deep in three of the four countries you include in this alliance. Any alliance between the PRC, Japan and the ROK would be fragile at best and subject to abandonment at the slightest of perceived provocations - Japanese PM visiting a war shrine in Tokyo, Japanese text-books, PRC and ROK maritime claims and surveys - you name it.

Your proposed alliance would also be a major disruption of the financial status-quo in East Asia. I believe, rhetoric aside, Japan and the PRC like the idea of a financial gateway into their countries via the ROC. Regardless of the public statements - business rules and quite a bit of it is done between the three.
