Wal-Mart Stores vice chairman Eduardo Castro-Wright is to retire from his position next year.

Castro-Wright, who is also CEO of the US retail giant’s global e-commerce and sourcing businesses, will retire on 1 July next year. The company said it expects to find a successor by the end of January.

Castro-Wright joined Wal-Mart in 2004 as president and COO of the retailer’s Mexican operations and was promoted to vice chairman three years ago. He assumed the e-commerce and sourcing roles in August last year.

“Eduardo has made many contributions at Wal-Mart, beginning in Mexico and continuing until today,” said Wal-Mart CEO Mike Duke. “He has been a strong advocate for our customers and in every assignment has brought passion and commitment to the job.”

The retailer also yesterday announced that Wan Ling Martello, COO of its e-commerce operations in emerging markets, is to replace Nestle CFO Jim Singh, who is retiring from the world’s largest food maker.
