On June 7, 2019, after three days of talks in Washington, Mexico and the United States issued a joint declaration.
Mexico committed to “el despliegue de la Guardia Nacional en todo el territorio nacional, dando prioridad a la frontera sur” (the deployment of the National Guard throughout the national territory, giving priority to the southern border). The US tariffs that were to take effect the following Monday were “suspendidas indefinidamente” (suspended indefinitely). (Video in Spanish.)
Further measures were to be “concluidas y anunciadas en un periodo de 90 días” (concluded and announced within a period of 90 days). A day before the deal, Foreign Secretary Marcelo Ebrard had announced that 6,000 members of the National Guard would go to the border with Guatemala. The declaration itself gives no number.
