Searching a Google country site: Localized & Regional Google Domains
Search the Top-level Regional Domain for each country, eg, .br for Brazil, .bo for Bolivia, .us for United States.
You can also use Language as a filter when searching for a web page; e.g. you can choose español (Latinoamerica). Note this does not mean that the site is based in a Latin American country…it simply means that is the language of the page.
