Wal-Mart Stores Inc. is increasing surprise inspections at thousands of foreign factories where it buys clothes, toys, shoes and other products as it expands efforts to make sure its suppliers uphold labor and environmental standards.
Wal-Mart expects unannounced inspections to make up 30 percent of all inspections this year, up from 20 percent last year and 8 percent in 2004, said Beth Keck, director of international corporate affairs for the world's largest retailer.
