About Sihanoukville
Sihanoukville (Krong Preah Seihanu; ក្រុងព្រះសីហនុ), formerly Kompong Som, is a seaside port city in Cambodia. This formerly laid-back beach destination has been transformed by Chinese investment and is now basically a giant construction site for Chinese resorts and casinos. It remains the launching point for beautiful islands nearby. In 2019, the city had about 67,000 residents.
