The New Zealand Dairy giant

The Fonterra Co-operative Group is one of New Zealand's largest milk processors and dairy exporters, producing more than 2 million metric tons of dairy products, specialty ingredients and consumer goods a year.

About 95 percent of its dairy products are exported to 140 countries, according to the company's website. It claims more than half of all pizzas sold in China are topped with Fonterra cheese.

China is Fonterra's biggest export market. Its Anmum Materna line of products for expectant mothers and the Anlene line of products for the elderly sell well in the country.
