Svay (pronounced Swai) Rieng is on of the smallest and sleepiest Cambodian provinces that just happen to have
one of the country's busiest highways running straight through - National Highway No 1, which links Phnom Penh and Ho Chi Minh City in Vietnam just after you cross the Mekong River by way of the Neak Loeung Ferry. It is also one of the poorest provinces of Cambodia due to the poor quality of the land. Most of the provincial population eke out a subsistence living based on farming and fishing.
Svay Rieng is the provincial capital, a sleepy town just 43 km from the Bavet border crossing. This is a fairly prosperous place as a result of the border trade traffic, business people and travellers passing trough. The town is a very friendly place and makes for a pleasant overnight stop whether coming from or going to Vietnam.
Svay Rieng town is situated near the Waiko River and its vast, scenic marshlands, the result of a wide stretch of the river drying up significantly over the years. It's a pleasant setting and one that can be enjoyed at several different spots along the river and marsh. A bridge over the Waiko, not far from the main part of town, bears a plaque that states prime minister Hun Sen donated the bridge.
During the long Vietnam War, American forces believed that this was the place, where Vietnamese communists had their intelligence headquarter. For sure there were undoubtedly a lot of Vietnamese communists hiding especially in the South of Cambodia during much of the war, but there wasn't a strategic centre like the Pentagon here. In 1969 the Americans began unauthorised bombing in this area and in 1970 joined with South Vietnamese forces for a big ground assault.
