On 4 October 2015, twelve countries representing 40% of the world’s economy signed the Trans-Pacific Partnership agreement. These countries consist of the United States, Mexico, Canada, Chile, Peru, Japan, Singapore, Brunei, Vietnam, Malaysia, Australia and New Zealand.
The signing of the TPP means that twelve countries with significant share in the world’s economy have been able to agree on one set of investment protection rules. As summarized on the U.S Trade Representatives website, the investment chapter will replicate the terms in the US 2012 Model Bilateral Investment Treaty. The rules require non-discriminatory investment policies and provide terms that assure basic rule of law protections. At the same time the rules ensure governments’ ability to achieve legitimate public policy objectives.
According to the Department of Foreign Affairs, Trade and Development of Canada, the investment chapter provides access to “an independent ISDS mechanism that is prompt, fair and transparent, and subject to appropriate grounds”.
This means that signing countries find ISDS to be relevant and necessary, not least between developed states. It may be noted that ISDS under the US 2012 Model Bilateral Investment Treaty includes a transparent proceeding and a possibility of a third party to participate in the proceeding. There is a good reason to guess the TPP will include these features too.
