King Norodom Sihamoni yesterday left for Vietnam on a three-day state visit to boost bilateral ties between both countries.
Prime Minister Hun Sen, National Assembly president Heng Samrin, Senate president Say Chhum and senior officials saw the King off at the Phnom Penh International Airport.
In a letter issued on Tuesday, the King said that he will visit Hanoi and Danang in Vietnam during the state visit which follows an invitation from the Vietnamese government.
He also said that Mr Chhum will become acting head of state.
“Following my absence, President of Senate Samdech Vibol Sena Pheakdei Say Chhum will receive help on my behalf as an acting head of state of the Kingdom,” the King said.
Mr Hun Sen posted on his Facebook account yesterday that the King’s visit is aimed at promoting better ties between Cambodia and Vietnam.
Last week, Mr Hun Sen paid an official visit to Vietnam and met with Vietnamese president Nguyen Phu Trong and National Assembly president Nguyen Thi Kim Ngan.
Mr Hun Sen also had a fruitful conversation with his Vietnamese counterpart, Premier Nguyen Xuan Phuc.
Six documents signed during Mr Hun Sen’s visit included agreements on transportation, border trade and the fight against the smuggling of ancient artefacts.
