Mondelez International's top-line performance in China has been patchy since the US snacks giant was established four years ago. Biscuits has been Mondelez's main business in China and challenges in the category meant, for example, the Oreo maker saw its sales in the country fall in 2014. A recovery from Mondelez's biscuit arm in China, plus growth from its chewing gum stable, helped the company's sales grow in 2015 - but sales fell in the first six months of this year. Speaking to just-food after announcing a significant push into China's chocolate market, Stephen Maher, the president of Mondelez's business in the country, discusses how he sees the prospects for the company in the market.
