"The Government of the United Mexican States, in accepting the provisions of Article IV, makes the express declaration that aliens who are required, for the performance of certain acts, to enter into the agreement or waiver referred to in Section I of Article 27 of the Political Constitution of the United Mexican States, must grant a special power of attorney, expressly including as one of its provisions the agreement and waiver above-mentioned. Section I of Article 27 of the Constitution reads as follows: "Only Mexicans by birth or by naturalization, and Mexican companies, have the right to acquire the ownership of lands, waters, and their appurtenances, or to obtain concessions for the exploitation of mines, waters, or mineral fuels in the Mexican Republic. The State may grant the same right to aliens, provided they enter into an agreement before the Secretariat of Foreign Relations to be considered as Mexicans with respect to such property, and not to invoke, therefore, the protection of their governments in any matter relating thereto; under the penalty, in the event they violate the agreement, of forfeiture to the nation of property they have acquired by reason thereof. Under no circumstances may foreigners acquire direct ownership of lands and waters within a zone of one hundred kilometers along the seashore."
