KING Father Norodom Sihanouk has written letters urging Prime Minister Hun Sen and other senior officials to examine opposition party allegations that Vietnamese authorities are encroaching on Cambodian soil.

The letters follow Cambodian and Vietnamese officials’ criticism of opposition leader Sam Rainsy for uprooting six markers along the countries’ loosely defined border in October.

Sihanouk’s letters urged officials to “consider” Sam Rainsy’s allegations. On Saturday, the opposition leader wrote a letter to the King Father, saying that villagers along the border in Svay Rieng province’s Chantrea district were losing valuable farmland to Vietnam.

Var Kimhong, the government’s senior minister in charge of border affairs, declined comment, noting only that Sam Rainsy’s letter mentions that villagers uprooted border posts – omitting his own involvement.
