Hi,
Thanks for the interest in our plugins.
We do not have shortcodes so it is difficult to have two calendars in one site as it is all custom coding, which we cannot support.
You could do two different sites to achieve that or a multisite.
If you would like one install you could use the Event Categories to only display the Events from either country.
For example the urls would be something like this using sample names:
yoursite.com/events/category/country1/
yoursite.com/events/category/country2/
You can test that out with the free version of the Events Calendar:
The Events Calendar
Let me know if you have any follow up questions.
Thanks
