ASP.NET MVC4 Searching for controller in wrong area

I'm using default MVC routing setup:

        routes.IgnoreRoute("{resource}.axd/{*pathInfo}");

        routes.MapRoute(
            name: "Default",
            url: "{controller}/{action}/{id}",
            defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }
        );

I have area defined as:

public class AdministrationAreaRegistration : AreaRegistration
    {
        public override string AreaName
        {
            get
            {
                return "Administration";
            }
        }

        public override void RegisterArea(AreaRegistrationContext context)
        {
            context.MapRoute(
                "Administration_default",
                "Administration/{controller}/{action}/{id}",
                new { action = "Index", id = UrlParameter.Optional }
            );
        }
    }

And I have a controller in that area:

namespace XXX.Areas.Administration.Controllers
{
    public class CountryController : Controller
    {
        public ActionResult Index()
        {
///
        }
    }
}

When I type

/Administration/Country

it works good as it is desired.

When I type

/Country

action still gets invoked, though view is not found so I get an error.

Why is MVC accepting

/Country

as valid route? I don't have another CountryController in non-area zone.
