The provisions of this section notwithstanding, the acquisition of citizenship by a natural born Filipino citizen from one of the Iberian and any friendly democratic Ibero-American countries or from the United Kingdom shall not produce loss or forfeiture of his Philippine citizenship if the law of that country grants the same privilege to its citizens and such had been agreed upon by treaty between the Philippines and the foreign country from which citizenship is acquired.
