Successful Surgical Intervention in Beijing

King Norodom Sihamoni has completed a successful surgical procedure in Beijing to address a recently diagnosed case of prostate cancer. According to a formal statement released by the royal palace in Phnom Penh, the operation took place on April 20 at a Chinese medical facility. Former Cambodian leader Hun Sen confirmed the positive outcome of the surgery, expressing gratitude toward the medical team for ensuring the safety of the 72-year-old monarch during the high-stakes procedure.

Extended Period of Clinical Monitoring

Following the operation, Chinese medical professionals have mandated that the King remain hospitalized for a period of intensive health monitoring. The monarch had previously informed the public that his treatment plan would likely require hospital stays lasting up to two months. This period of clinical observation is designed to ensure a stable recovery and to allow doctors to provide the prolonged specialized care necessary for his specific oncological diagnosis.

Diplomatic Support from Cambodia's Political Elite

The significance of the King's health was underscored by a high-level visit from Cambodia’s most influential political figures. Former leader Hun Sen and his son, current Prime Minister Hun Manet, traveled to Beijing to offer support to the monarch during his recovery. In a social media post, Hun Sen emphasized the symbolic weight of the King’s well-being, stating that the health of the King is the health of the whole nation, while indicating his intention to return home once the monarch's condition shows further improvement.
