The Trans-Pacific Partnership (TPP) is an ambitious free trade agreement that has been in negotiations since 2010 among 12 countries, namely: Canada, the United States, Australia, Brunei Darussalam, Chile, Japan, Malaysia, Mexico, New Zealand, Peru, Singapore and Vietnam. Collectively, these nations represent approximately 40 per cent of the world’s gross domestic product (GDP) (roughly C$28.5-trillion), one-third of all international trade and over 775 million consumers.
