An article in the Atlantic (December 2011) suggests that 70 % of Walmart’s $420 billion in sales are provided by 20,000 Chinese suppliers. Walmart’s efforts at decreasing waste, pollution etc thus impact its supply chain in China significantly, and increase compliance without any government role. But will improved environmentally compliant supply chains in China buy US customer loyalty? Will the possibly slightly higher prices hurt US demand  ? Will increased Chinese customer demand provide profits to cover the potentially higher supply chain costs or will the costs drop in the long run?
