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

The newspaper said that based on its own investigation technology had been stolen by high-level Chinese employees in the research and development department and leaked to the Chinese government.

"ASML found no hard proof of involvement of the Chinese government," the newspaper quoted the Veldhoven-based company as saying.
