PRIME Minister Hun Sen opened a new US$8.7 million South Korean culture, tourism and trade centre Monday in Phnom Penh. Kim Kwan Yung, governor of Gyrong San Bukdo province, which backed the project to build ties with Phnom Penh, said the centre would help promote business relations between the two countries. The three-storey centre built by DKC & C Co, a South Korean construction firm, will feature a department store, a public Internet hub, a VIP area, conference hall and a display area for cultural works from Cambodia and South Korea.
