Sihanouk at keyboard in Beijing

Sihanouk :  Cambodia population under Sangkum  were 7 million  Deaths under Lon Nol, Pol Pot and Viet occupation  estimated at 3 million  So it should be only 4 million in 1991  How come they say Cambodians are now 13 million  with infant mortality the worst in the world?  I see only one explanation : the excess people were imported  under the protection of Viet troops  and voted massively for Hun Sen!
The High Rock girl, pointing her finger : Yé! Yé! Yé!  And you were the Father  of the New Cambodians that we are!  Yé! Yé! Yé!
