There are literally thousands of products which the US exports to Mexico. Broadly speaking, the US exports food items, machines such as computers and cars etc., as well as parts for machines, books, movies, etc. Remember, the US consists of 50 states, and each state produces many different things. The US economy is for now the largest of any country (although China is expected to surpass the US in the near future) and so it produces really a lot of different things.
what sells more in the us ketchup or salsa? Ketchup! :-)
Mexico
do this and that for me
You mean electric power? Yes; it goes both ways. The US sells power to Mexico and also purchases power from Mexico. One example is the San Diego-Tijuana power grid, which is shared among both countries and is part of the larger Southwest grid, serving the US states of California and Arizona, as well as the Mexican states of Baja California and Sonora. All four states were impacted during the "2011 Southwest Blackout"
Mercado Libre (Mexico's version of Amazon) qualifies as such.
Uses, consumes and sells them
There is a store in Juarez Mexico that sells Rey Mysterio masks, pants, gloves, and T-shirts. I don't remember the name of the store, but yes, there is a shop in Mexico that sells Rey Mysterio merchandise. It is NOT a Rey Mysterio shop that's all about him. It's a market that sells merchandise of him.
Mexico is south of the US. consequently the US is north of Mexico
Export is the sell of goods and services to an international buyer. For example, when Mexico sells a car to the United States, it is exporting a car. Mexico is one of the largest exporters in the world, ranked as the 15th largest with US$336.3 billion (2011) worth of exports.
You mean a trade deficit and yes, Mexico has it.
No. The US is north of Mexico.
The Chevrolet Tornado is actually sold in Mexico as the Tornado, and other countries in Latin America as the Montana. I am from Mexico and one of my uncles in Mexico drives a white Chevrolet Tornado, it's pretty cool. It is not sold in the United States because it would hurt the prices and sells.
