THE health of Senate President Chea Sim has improved after he experienced circulation problems and flew to Singapore for emergency treatment on Monday.

Cambodian People’s Party lawmaker Cheam Yeap said the 78-year-old would remain in hospital for further tests and was awaiting permission from his doctors to return to work in Cambodia. “He is aging, but his children and colleagues [are] taking care of him with an expert doctor standing by,” Cheam Yeap said. Chea Sim has suffered from high blood pressure and diabetes for years. Last December, he flew to Singapore for a similar treatment.
