You already have everything you need.  Your selectlist has a getter and setter in your controller, based on "countries", if you reference the object directly, you will get the value set in the page. One thing though, because you are setting up countries as a string array, it appears you were expecting the list to be a multiselect.
If you really only want one result from the selectlist, update your controller like this, and your code will work:
Code:
public class sampleCon {
 
    String countries;
 
    public PageReference test() {
        return null;
    }
 
    public List<SelectOption> getItems() {
        List<SelectOption> options = new List<SelectOption>();
        options.add(new SelectOption('US','US'));
        options.add(new SelectOption('CANADA','Canada'));
        options.add(new SelectOption('MEXICO','Mexico'));
        return options;
    }
 
    public String getCountries() {
        return countries;
    }
 
    public void setCountries(String countries) {
        this.countries = countries;
    }
 }
