Retailer sets high standards

Global retail giant Wal-Mart Stores Inc said it will impose higher environmental and social standards on its 20,000 suppliers in China in a bid to build a more environmentally and socially responsible global supply chain.

The standards are due to take effect next month to ensure Chinese clothing, toys and appliances' global quality. And the standards are soon expected to cover all of the company's items.

The US chain store also said it wants suppliers to take more responsibility and play a bigger role in ensuring their sub-contractors are complying with standards.
