Many Chinese see in the agreement a government desperate to buy international peace before the Olympics, at any price. One post (原贴) from Tianya:
The Olympics is only a game, how can it be used to kidnap China; how can it lead to such a heavy loss in Chinese interests?
China has 100% sovereignty over the East China Sea continental shelf, this is our most fundamental principle. Once China makes a mistake on this basic principle, then the consequences are long-lasting and severe. This naturally implies China will fall into the hopeless situation of having to negotiate. Once China accepts Japan’s demand for “joint development”, it inevitably dilutes China’s sovereignty over the East China Sea continental shelf.
The Chunxiao natural gas fields have already been fully developed by mainland China, why is there any talk of joint development? Japan’s is using its claims of sovereignty to request a taste of Chunxiao’s rewards. I absolutely can not accept this perspective.
If China agrees to sharing the East China Sea oil and gas fields, this is equivalent to recognizing Japan’s sovereignty over the continental shelf. This is a very serious strategic mistake, with unimaginable consequences.
