Japan agreed. but 1951.9.8 Japan signed with the United States the San Francisco peace treaty .USA would control Dy .The Chinese government believes it's illegal, invalid, it is absolutely not admit 1971.6.17 USA gave it back to Japan 1971.12.30 Chinese foreign ministry strongly condemnded USA goverment and the japan goverment, these days there ia an old chinese book called Six Chapters of a Floating Life in that book ,it proves china finded Dy 76 earlier than japan these are the history about the Dy i just feel very puzzled , why there are so many contradictions between,when can we get along with each other
