AKP Phnom Penh, August 21, 2026 —

His Majesty Preah Bat Samdech Preah Boromneath Norodom Sihamoni, King of Cambodia, has said that the newly built Solidarity Palace of the Senate reflects the core values and leadership philosophy of Cambodian leaders, who recognise national unity and solidarity as strong pillars of the Kingdom’s long-term peace, stability and prosperity.

The King made the remarks while presiding over the official inauguration ceremony of the Solidarity Palace on Friday.

His Majesty said the building would serve not only as a symbol of national solidarity, but also contribute to enhancing Cambodia’s prestige on the international stage and adding to the architectural heritage of the Chamkar Mon State Palace.

“We can conclude that the Solidarity Palace will not only be a symbol of national solidarity, but this building will help enhance national prestige on the international stage, now and in the future, and help add beauty and diversity to the many historical buildings in the Chamkar Mon State Palace, which is a legacy of architecture and the most precious masterpiece of His Majesty King Norodom Sihanouk ‘Preah Borom Ratanak Kaudh’,” the monarch underlined.
