Wal-Mart Stores Inc, the world's largest retail outlet, is looking to increase its presence in China's growing e-commerce market by focusing more attention on its relationship with online grocery store Yihaodian. Wal-Mart first invested in Yhd in 2011, increasing its stake to more than 51 percent in 2012. "Building the fulfillment network for grocery fast-moving consumer goods is the hardest network to build, and that is what Yihaodian has done, " Dan Toporek, a spokesman for Wal-Mart's global e-commerce office, told China Daily. Yihaodian is now building on top of and expanding that network, and expanding the items customers can purchase through it, " Toporek said. Yhd has chosen to augment its position as an online grocery store with a number of departments, including appliances and clothing. Kelland Willis, a global e-commerce analyst with Forrester Research, a US-based advisory firm, said the move into consumer products could have some potential hurdles for Yhd.
