TOKYO (Reuters) - The head of Japan's Hitachi Ltd <6501.T> said the company was aiming to improve its operating margin to double digits by fiscal 2021 from current levels of around 7 percent.


Chief Executive Toshiaki Higashihara, in an interview to reporters, also said Hitachi was not interested in assets being put up for sale by General Electric <GE.N>.


The U.S. conglomerate wants to get rid of at least $20 billion of assets through sales, spin-offs or other means to turn itself into a smaller, more focused company.
