The National Registry of Foreign Investment («RNIE», for its acronym in spanish) is the area of the Mexican Federal Government, administered by the Ministry of Economy, in charge of accounting and following up on foreign investment flows in Mexico. It was created in March 1973, with the publication of the Law to Promote Mexican Investment and Regulate Foreign Investment (replaced by the current Foreign Investment Law), with the main purpose of monitoring compliance with the provisions on foreign investment and to have a source of information that would allow to know the behavior of foreign investments in the country.
