What two COUNTRIES border North and South America. Technically, Mexico is in Central America, so the answer to the question is: Mexico borders North America, and Panama borders South America. Some consider Mexico to be a part of North America, which is technically incorrect, but in that case, then there are three countries that border North and South America: Panama borders South America, and Belize and Guatemala border North America (Mexico).
The USA (United States of America) borders Mexico in the north Guatemala & Belize border Mexico in the south.
The United States borders Mexico on the north, Guatemala and Belize on the south
That would be most countries where Mexico does not have a direct representation (i.e. where Mexico has no embassy nor diplomatic relations). That would include most African countries such as Mozambique or Libya and some Central and South Asian countries, such as Kazakhstan, Mongolia and Papua New Guinea.
Canada and Mexico are foreign countries that border the U.S.A. Canada is to the north and Mexico is to the south.
There are 3 countries that border Mexico: The US to the north, and Guatemala and Belize to the south.
The countries adjoining North and South America are Mexico, El Santiago, Panama, Costa Rico, Guatemala, Honduras and Nicaragua.
Most countries in South America share some traits with Mexico. Some include language, religion and general culture, such as Colombia, Venezuela and Ecuador. Some others are "newly industrialized countries", which have more developed economies like Mexico, such as Argentina, Chile and Uruguay. You must understand that every country is different from each other, at least on small details, and this too is the case: Argentina is to Mexico what Canada is to the United States; Brazil is to Mexico what Portugal is to Spain.
Mexico is one country it does not contain any others.
