Retail giant Walmart is spending US$16.3 million across stores in China to reassure customers its products are safe.

The move follows after a series of food safety scandals in the nation.

Part of the amount will be used to run third-party food-quality tests at 70 stores in Guangdong. Other funds will be dedicated to improve food safety practices in stores by increasing employee training, hiring more retail compliance experts and adding another fresh-food testing center, its seventh.

Walmart has been under fire in China for selling alledgely expired eggs in baked goods sold to consumers. In 2011, it was also reported that some Walmart workers in Chongqing were arrested for mislabelling ordinary pork as organic.

Walmart said in April that it plans to invest 500 million yuan ($80 million) to remodel 50 of its 380-plus stores in China and said it will open 30 new stores in the country this year.
