Wal-Mart promotes exec of Asia division Greg Foran as new CEO of Wal-Mart US stores

Wal-Mart Stores Inc. says U.S. discount-store chief Bill Simon is stepping down.

The world's largest retailer has named the head of its Asian business as his replacement.

The Bentonville, Arkansas-based retailer says that Greg Foran, 53, president and CEO of Wal-Mart Asia, will succeed Simon.

Simon helmed the Wal-Mart U.S. division since June 2010. The changes will take effect Aug. 9. The company says Simon will be available on a consulting basis for the next six months to ensure a seamless transition.

Foran will report directly to Doug McMillon, who took over as president and CEO of Wal-Mart Stores Inc. in February.
