On November 26, 1990, President Carlos Salinas de Gortari received President George H. W. Bush in Agualeguas, Nuevo León. According to a statement by the White House press secretary, Salinas hosted a lunch for Bush at the Salinas family home.
The two men had first met in Houston in November 1988, when both were presidents-elect. A 2017 article in the Revista Mexicana de Sociología notes that the talks of that meeting “fueron denominadas con el tiempo como el ‘Espíritu de Houston'” (came in time to be called the “Spirit of Houston”).
