Mexico Signs ICSID Convention

By January 22, 2018October 9th, 2020Chang Law

On 11 January 2017, Mexico signed the Convention on the Settlement of Investment Disputes between States and Nationals of Other States (“ICSID Convention” or “Convention”). Mexico still has to ratify the Convention (See Article 68.1), but once it does, it will become the 154th Contracting State to the Convention.

Mexico’s decision was likely influenced by the ongoing NAFTA negotiations, whose 6th round of negotiations will start up again 23 January 2018. Mexico’s signature also appears to show a vote of confidence in the legitimacy of the investment-treaty system at a time when Investor-State Dispute Settlement Reform is actively being debated by delegations at the United Nations Commission on International Trade Law (“UNCITRAL”).

Once Mexico ratifies the Convention, all NAFTA states will be Contracting States to the ICSID Convention. The United States signed the ICSID Convention in 1965 and ratified it in 1966. Canada signed the Convention in 2006 and ratified it in 2013. Once Mexico fully ratifies, any disputes among the NAFTA states could then be resolved using the ICSID Arbitration Rules (which requires both parties be associated with Contracting States to the Convention), rather than the ICSID’s Additional Facility Rules (which only requires one party to be an ICSID Contracting Party).
