David Duong's family had to be rescued at sea after fleeing Vietnam in a small boat at the end of the war.

Now, the family recycling business in California is worth hundreds of millions of dollars, employs hundreds of people, and is investing back in Vietnam. VOA's Jim Randle reports from Oakland, California.
