Walmart, Amazon and Home Depot have all introduced new efforts to put the pressure on their Chinese suppliers, including cutting orders or negotiating lower prices. Walmart and Home Depot have reportedly advanced some of their planned purchases to accelerate their supply chains with Chinese vendors, according to a Walmart spokesperson and comments made during Home Depot's latest earnings call, The WSJ said. Amazon, meanwhile, has cut back some of its orders for certain private-label products, one unnamed source said, noting that the eCommerce giant can no longer make a profit on some of these products as a result of trade tariffs. Dollar Tree and Target have taken similar measures as a result of trade disputes. Reports said Dollar Tree provided an email statement confirming renegotiations with its vendors, as well as cancelled orders and adjusted product lineups. Target emailed reporters saying it has "many levers" to remain competitive on price, but did not offer more details.
