Former king Norodom Sihanouk, who said last month he beat a third round of cancer, will be allowed to visit Cambodia for two months, before returning to China, according to his Web site.

Sihanouk, 86, has been undergoing treatment in Beijing for B-cell lymphoma, a cancer that hits the blood cells of the immune system, Agence France-Presse reported in June.

His doctors will allow him to stay in Cambodia for two months, after which he will return to China, according to a letter on the former king’s Web site.

After a two-month sojourn in their Siem Reap palace, the former king and queen will travel back to China, along with King Norodom Sihamoni, who will also received a medical check-up, the letter, hand-written in French, said.

Sihanouk was a key player for decades in Cambodian politics, and is sometimes referred to as “father of the nation.” He abdicated in 2004, giving his throne to Sihamoni.
