Mexico’s president threatened to declare a disputed property owned by Vulcan Materials Co. an environmentally protected area, after failing to reach an agreement with the US construction firm.

Andres Manuel Lopez Obrador said Vulcan continued work at the site even while in talks with his government over its potential purchase of the property, which was occupied by Mexican marines in March. Accusing the company of “vile trickery,” AMLO — as the president is known — told reporters Friday that he would act by decree if necessary to halt the destruction in “one of the most beautiful areas in the world.”

His comments came a day after Bloomberg reported that the Alabama-based firm was seeking the Biden administration’s protection from what it sees as the threat of a hostile takeover of its property. The 2,400 hectare (5,930 acre) plot south of the resort city of Playa del Carmen includes a port and a quarry.
