The abolitionists in the North fairly well guaranteed that northern states would not have slavery, and it began to be unpopular in the border states as well. The only way that the South could prevent anti-slavery moves in Congress would be to maintain equality of representation, that meant adding new states where slavery would be allowed.
Under the Missouri Compromise (1820), no slave states other than Missouri would be allowed north of the dividing line of 36° 30' N latitude. So any new slave states would have to come from lands, including Texas, that were then controlled by Mexico. Following the annexation of Texas (1845) and the Mexican Cession (1848), the New Mexico Territory offered the possibility of new slave states.
The South was as interested in the US' western territories as were Northerners. The souther half of the west had the climate for great crop production. They saw the new territories as a good place for slave driven farm crops.
The Gadsden Purchase saw the purchase of land from Mexico by the United States. Most of the land acquired from this purchased exists in southern Arizona just below Phoenix. The remaining land exists in New Mexico.
The purchase was arranged by James Gadsden, Ambassador to Mexico and it extended the southern borders of present day Arizona and New Mexico for the purpose of constructing a transcontinental railroad.

Canada in the north and Mexico in the south have land borders with the US.
There's the Pacific Ocean, the Atlantic Ocean, and the Gulf of Mexico.
As far as land borders, there are only two: Canada on the north and Mexico on the south.

No. New Mexico is in the western USA and not on the eastern (Atlantic) side. It is land locked and only has the Rio Grand River as a border on the south. See the link below for information:

Mexico is the bordering nation that is south of the US. However, other nations are also just south of the US, though not by land borders. For example, Cuba.
Directly bordering it? That would be Mexico. Other countries south of the US but not directly touched by its land borders would also include The Bahamas and Cuba.
