US retail giant Wal-Mart said Wednesday it would step up efforts to ensure the quality of products it sources, including in China, where a milk scandal has again highlighted weak standards.
"Today, we're asking suppliers to take those standards to an even higher level," Wal-Mart Vice Chairman Mike Duke told a conference in Beijing.
"We will require greater transparency and ownership from our supplier partners."
Wal-Mart will begin the move towards improved transparency in November with apparel, gradually expanding it to other product categories in a process expected to be completed by end-2009.
"It will mean that if you sell us tennis shoes, we expect you to know — and we expect you to tell us — not just where the tennis shoes were assembled, but which sub-contractors played a role in making them," he said.
"Essentially, we expect you to ask the tough questions, to give us the answers and, if there's a problem, to own the solution."
Wal-Mart would also require its Chinese suppliers to clearly demonstrate that they were complying with the nation's environmental laws and regulations, he added.
China, where Wal-Mart sources a large portion of its merchandise, has been rocked by a series of product quality scandals in recent years, most recently over tainted baby formula that sickened thousands of infants and killed four.
