No, he's not a regular. The actor, though, has appeared in dozens of movies and TV shows for a couple of decades.
His name is James Hong. Some of his TV creds include the original Outer Limits, Hawaii Five-O, Cannon, Barnaby Jones, Switch, Fall Guy, and too many damned others. Among the movies he's appeared in is "Tango and Cash", with Kurt Russell and Sylvester Stallone.
Best,
Mark
