Sand-dredging boats were active along the Mekong River in Phnom Penh’s Meanchey district on Tuesday, despite the city’s municipal governor, Pa Socheatvong, having ordered a complete suspension of dredging in the city the day before. Phnom Penh City Hall on Monday put in place the temporary ban on all dredging in response to what it said was an overabundance of unlicensed firms dredging river sand in the capital.
