The common trading market here would be the EU, which I'm assuming stands for European single market, within the European Union.

ANZUS- ANZUS is a collect non-binding security agreement signed by New Zealand, Australia, and the United States in 1951 to co-operate on military matters in the pacific region in the ocean.

NATO - NATO is the North Atlantic Treaty Organization. It's an international alliance consisting of 29 states from North America and Europe. It was established on April 4, 1949.

GATT- GATT is The general agreement on tariffs and trade, and is a legal agreement between multiple countries with the overall purpose to promote international trade by reducing or eliminating trade barriers like tariffs and/or quotas
