The countries that use Spanish as the official language are Argentina, Bolivia, Chile, Colombia, Costa Rica, Cuba, Dominican Republic, Ecuador, El Salvador, Equatorial Guinea, Guatemala, Honduras, Mexico, Nicaragua, Panama, Paraguay, Peru, Spain, Uruguay and Venezuela.

Spanish is also spoken in Andorra, Belize, Canada, Gibraltar, Israel, Morocco, the Netherlands, the Philippines, Puerto Rico, the United States, Trinidad and Tobago and Western Sahara.

There are many different Spanish dialects in Spain and America. The pronunciation of Castilla dialect in northern Spain is usually considered as the standard pronunciation of Spanish. In America, the first Spaniards brought their localism. Today, you can still find that there are obviously different dialect accents in different parts of America.

Spanish varies slightly from region to region. The Spanish accent in Spain is different from that in Latin America. There are also differences between Mexico and Argentina. But believe me, the differences between Spanish and Chinese are nothing compared with the dialects in different parts of China-the dialects in another place which is 1KM away.
