Having helped peace to return after the rebellion, Duong Chark received the Legion of Honour from the French authorities as a sign of their gratitude and the clemency of Gouverneur Général Georges Jules Piquet.
[8] Unsatisfied with the French protectorate and the contempt of the Khmer royal family, especially coming from the Résident Supérieur, Albert Louis Huyn de Vernéville, Duong Chakr was travelling to protest his extradition from Cambodia.
Meanwhile, governor-general of French Indochina Jean Marie Antoine de Lanessan reported that the King of Cambodia who had repudiated his son was not favorable to such a warm welcome in France.
He was driven to Djelfa on the northeast edge of the Sahara and with the dry, steppe-like Hautes Plaines to the North, "in one of the worst possible exilic locales" where it was impossible to "escape the hopeless monotony".
In exile, the couple gave birth to a child whom they desired to raise in the Catholic faith and named after the French President, Princess Norodom Mon Thun.
Seven years after him, his brother Prince Yukanthor, who had become the new favourite for succession to the Khmer throne, would suffer an equivalent humiliation and dismissal from the French Republic.
