The world's 20 wealthiest economies accounted for about half of the people worldwide living in "modern slavery," according to a new report.

The report released this week by Walk Free, an international human rights group, found that countries belonging to the Group of 20 major economies helped fuel forced labor through global supply chains and state-imposed forced labor. Between the 20 countries, they imported $468 billion worth of products possibly made by forced labor, with the U.S. making up nearly $170 billion of that, the report said.
