Normally woocommerce do it itself, and nothing is needed…
But you can try the following instead, that should work in Woocommerce 3+ versions:
add_action('wp_footer', 'billing_country_update_checkout', 50);
function billing_country_update_checkout() {
if ( ! is_checkout() ) return;
?>
Code goes in function.php file of your active child theme (or active theme). Tested and works.
