SIHANOUKVILLE – Foreign Minister Hor Namhong led a government delegation that spoke with Vietnamese counterparts in a two-day meeting of the Cambodia-Vietnam Joint Commission on Economic, Cultural, Scientific and Technology Cooperation that started Thursday in Sihanoukville. The 11th such meeting of its kind between the two neighbours was co-chaired by Vietnamese Deputy Prime Minister Pham Gia Khiem, and both sides agreed to strengthen cooperation in the four sectors in a bid to counter bilateral trade that has fallen nearly 30 percent in the first 10 months compared to the same period last year to US$1.049 billion.
