Move specific records on top of the list beside ORDER BY

Suppose you have all countries name in MySQL db table like:

and you want to show some specific countries on top of the list and remaining countries will start after them. So this query can do it.

SELECT * FROM countries
ORDER BY country_name = 'Australia' desc,
         country_name = 'United arab emirates' desc,
         country_name = 'Pakistan' desc,
         country_name = 'United kingdom' desc,
         country_name = 'United states' desc,
         country_name asc;
