It depends on whether you are referring to the Amazon Basin or the Amazon River. The Amazon Basin occupies sections of Brazil, Peru, Colombia, Venezuela, Ecuador, Bolivia, Guyana, Suriname, and French Guiana. It is nowhere near Mexico. The Amazon River does not border any of these countries. Its path takes it through Brazil and Peru, and other rivers from Venezuela do flow into it, but it is nowhere near Mexico.
