King Father Norodom Sihanouk said Saturday that he plans to return to China towards the end of the month for health checks after a three-month stay in Cambodia. “My Chinese physicians have made efforts to cure my three cancers,” Sihanouk, 87, said in a televised address to an audience of Buddhist nuns at the Royal Palace. “Now they have requested that I go to China again at the end of June or early July in order for them to take action through their scientific skills to prevent the return of the cancer.” Prince Sisowath Thomico, an adviser to the King Father, said Sihanouk will return to China after finishing a scheduled visit to neighbouring Vietnam, but added that he did not know the exact dates for either trip.
