On May 18, 2018, the Department of State and the US Trade Representative (USTR) published in the Federal Register a notice of termination [Public Notice 10418] of the “Treaty between the United States of America and the Republic of Ecuador Concerning the Encouragement and Reciprocal Protection of Investment” (“the Treaty”). Ecuador delivered a notice dated May 18, 2017, that it was terminating the Treaty. Pursuant to the terms of the Treaty, termination takes effect one year from the date of that notice. As a result, the Treaty terminates as of May 18, 2018, except that it will continue to apply for another 10 years to investments made or acquired prior to the date of termination (May 18, 2018) and to which the Treaty otherwise applies. The Treaty provides protections to cross-border investment between the two countries and the option to resolve investment disputes through international arbitration. State and USTR, which co-lead the U.S. bilateral investment treaty program, are providing this notice so that existing or potential U.S. investors in Ecuador can factor the termination of the Treaty into their business planning, as appropriate.
