Mexico has replaced China as the #2 foreign trading partner of the United States… where it normally has been for the last century.
I’ve said that Mexico’s overly-close economic (and geographic) relationship to the U.S. has been the source of most of the nation’s woes over the last 200 years, and that Mexico needs to expand trade outside of NAFTA, so whether this is good news or not, I can’t say.

They said that it’s for a weak peso, expensive oil and heavy stuff exports and will not last too much. What do you think?
Who is the first US trading partner?
Canada, by far the largest supplier of U.S. foreign oil (and terrorists).
