Mexican Secretary of Foreign Affairs Luis Videgaray Caso praised the relationship between his country and the United States, but said one item not on the table in the trade understanding between the two nations announced Monday was clear: Mexico will not pay for a wall.

“We just reached a trade understanding with the US, and the outlook for the relationship between our two countries is very positive,” he said in a Tweet. “We will NEVER pay for a wall, however. That has been absolutely clear from the very beginning.”
