The Trans-Pacific Partnership, one of the world’s biggest multinational trade deals, was signed by 12 member nations on Thursday in New Zealand, but the massive trade pact will still require years of tough negotiations before it becomes a reality.
The TPP, a deal which will cover 40 per cent of the world economy, has already taken five years of negotiations to reach Thursday’s signing stage.
The signing is “an important step” but the agreement “is still just a piece of paper, or rather over 16,000 pieces of paper until it actually comes into force,” said New Zealand Prime Minister John Key at the ceremony in Auckland.

The 12 nations include Australia, Brunei, Canada, Chile, Japan, Malaysia, Mexico, New Zealand, Peru, Singapore, the United States and Vietnam.
Given their size, both the United States and Japan would need to ratify the deal, which will set common standards on issues ranging from workers’ rights to intellectual property protection in 12 Pacific nations.
Opposition from many US Democrats and some Republicans could mean a vote on the TPP is unlikely before President Barack Obama, a supporter of the TPP, leaves office early in 2017.
