WooCommerce set a min order price for a single country

I’m trying through this code to set a minimum price for orders:

// Set a minimum dollar amount per order
add_action( 'woocommerce_check_cart_items', __NAMESPACE__ . 'spyr_set_min_total' );
function spyr_set_min_total() {
    // Only run in the Cart or Checkout pages
    if ( is_cart() || is_checkout() ) {
        global $woocommerce;

        // Set minimum cart total
        $minimum_cart_total = 10;

        // Total we are going to be using for the Math
        // This is before taxes and shipping charges
        $total = WC()->cart->subtotal;

        // Compare values and add an error is Cart's total
        // happens to be less than the minimum required before checking out.
        // Will display a message along the lines of
        // A Minimum of 10 USD is required before checking out. (Cont. below)
        // Current cart total: 6 USD 
        if ( $total <= $minimum_cart_total  ) {
            // Display our error message
            wc_add_notice( 
                sprintf( 
                    'You have not yet reached the minimum order of € 10,00.' . 
                        'Your order is: %s %s',
                    $total,
                    get_option( 'woocommerce_currency' ) 
                ),
                'error' 
            );
        }
    }
}

So everything works, but I need to enable it only for orders placed in UK.

I thought that the solution could be adding these variables:

$states = array( 'UK' );
$shippingaddr = WC()->customer->shipping_state;

if ( is_cart() || is_checkout() || $shippingaddr = $states ) {

but it’s not working. Any suggestions?

EDIT.

CORRECT CODE

// Only run in the Cart or Checkout pages
    global $woocommerce;
    if( ( is_cart() || is_checkout()) && "UK" == WC()->customer->shipping_country ) 
    // Set minimum cart total
    $minimum_cart_total = 10;
