Chinese officials “desperately wanted” the technical know-how to cleanly manufacture white pigment and California engineer Walter Liew told them he could provide it, a U.S. prosecutor told jurors.
Except Liew didn’t have the knowledge, the prosecutor said. So he stole it from DuPont Co., the world’s largest producer of the pigment, and gave it to a Chinese state-owned company for $28 million in contracts, Assistant U.S. Attorney John Hemann said yesterday in San Francisco, where Liew is on trial, accused of conspiracy, economic espionage and trade secret theft.
