What is Cairns Group?

Legal Definition
The Cairns Group (Cairns Group of Fair Trading Nations) is an interest group of 20 agricultural exporting countries, composed of Argentina, Australia, Bolivia, Brazil, Canada, Chile, Colombia, Costa Rica, Guatemala, Indonesia, Malaysia, New Zealand, Pakistan, Paraguay, Peru, the Philippines, South Africa, Thailand, Uruguay, and Vietnam.

The Cairns Group seeks to liberalize global trade in agricultural produce. In particular, its members aim to abolish export subsidies and trade-distorting ("amber box") domestic support for agricultural products and seek to improve market access for agricultural exports. The coalition attempts to present a common front in multilateral trade negotiations at the World Trade Organization (WTO), tabling joint proposals and occasionally working with like-minded groups such as the G20 group of developing nations.
