There are template filters for all types of queries. You could use archive_template
in this case.
function wpd210689_template_filter( $archive_template ) {
$post_types = array( 'america', 'china', 'nepal', 'norway', 'chile' );
if ( is_post_type_archive ( $post_types ) ) {
$archive_template = locate_template( 'archive-country.php' );
}
return $archive_template;
}
add_filter( 'archive_template', 'wpd210689_template_filter' ) ;
