China dominated our headlines in the first part of the week. Swiss firm Hero Group was forced to defend the safety of its infant formula in the country after allegations a local distributor mislabelled products. Wal-Mart, meanwhile, issued a statement to reiterate its expansion plans in China after it emerged it would close three stores there. Emerging markets continued to feature heavily, with news Qatar had bought a majority stake in Indian group Bush Foods Overseas. And we interviewed the CEO of ambitious Brazilian dairy group Vigor.
