CHICAGO (AP) -- A Taiwanese man accused of trying to bypass bans on supplying weapons machinery to North Korea is expected to change his plea to guilty.
A court document says Hsien Tai Tsai will attend a change-of-plea hearing Thursday in federal court in Chicago.
The 68-year-old man has been charged with conspiring to thwart laws on the proliferation of weapons of mass destruction. It's unclear what counts Tsai will plead guilty to.
He was arrested while visiting Estonia. The Baltic Sea-coast nation worked with the U.S. to capture him, then jailed him for five months. Estonia extradited Tsai a year ago.
Tsai's son was arrested in the Chicago area last year on similar charges.
Defense attorney Steven Shobat didn't immediately respond to a message left Wednesday seeking comment.
