South Australians are being urged not to boycott Farmers Union Iced Coffee, following news that a Chinese-owned company would be taking over its parent company.

The news of changing parent companies was met with anger on social media, with many users vowing to stop buying the iced coffee altogether.

The company taking over the business, China Mengniu Dairy, responded to facebook comment on its page saying, "we are currently part of Lion, which is Japanese-owned and they have announced the Dairy & Drinks business is being sold to Mengniu Dairy, pending regulatory approvals.”
