Cambodia inaugurated a 45-kilometer upgraded section of the China-funded National Road 7 on Tuesday, with Prime Minister Hun Manet hailing it as a key project boosting trade, tourism, and regional connectivity.

Speaking at the inauguration ceremony in Kampong Cham city in southeastern Cambodia, Hun Manet said the upgraded section — stretching from the Skun Market roundabout to the Kizuna Bridge roundabout in Kampong Cham city — connects the central region to the northeastern provinces, serving as a vital economic artery.

"This road will facilitate public transit, stimulate trade and tourism, and enhance the quality of life for residents and commuters," he was quoted by Xinhua News Agency as saying.

The National Road 7 is a key transport thoroughfare connecting the capital Phnom Penh with Kandal and Kampong Cham provinces that also links Cambodia to the Lao border. The 196-km road is an early Chinese aid project, with construction beginning in 2004. It has been one of the busiest roads in the kingdom since it opened in 2008.
