Drupal block of insertable code to query a content type against a field value and return matching field values. In this case, use the Smart IP module to grab the user country, and find international fields.

<?php

// get country (requires Smart IP installed)
$smart_ip_session = smart_ip_session_get('smart_ip');
$user_country = $smart_ip_session['location']['country'];

// execute a query against the international_data content type using field_location_name
$query = new EntityFieldQuery();
$query
  ->entityCondition('entity_type', 'node')
  ->entityCondition('bundle', 'international_data')
  ->fieldCondition('field_location_name', 'value', $user_country);

$result = $query->execute();

if (!empty($result)) {
  $nids = array_keys($result['node']);
  $node = node_load($nids[0]); // loads only the first result
  $fieldValueA = $node->field_value_a[$node->language][0]['value'];
  $fieldValueB = $node->field_value_b[$node->language][0]['value'];
}

echo '<h2>' . $fieldValueA . '</h2>';
echo '<h2>' . $fieldValueB . '</h2>''
