Chinese employees stole corporate secrets from Dutch semiconductor equipment maker ASML, resulting in hundreds of millions of dollars in losses, Dutch financial newspaper Financieele Dagblad (FD) reported on Thursday.

The paper said, citing its own investigation, technology had been stolen by high-level Chinese employees in the research and development department of ASML's U.S. subsidiary and ultimately leaked to a company linked to the Chinese government.

But ASML itself "found no hard proof of involvement of the Chinese government," the FD reported.
