Phnom Penh - Cambodia has outlawed sand exports from a coastal region where it has been primarily funnelled in huge quantities to Singapore, a move met with scepticism from activists who said previous bans on the destructive industry had failed to take root.
Environmental groups have long accused Cambodia of running damaging and corrupt sand dredging operations along the southwest coast and the Mekong river.
Most of the sand has been shipped to Singapore to fuel the wealthy city-state's rapid expansion - a resource plunder that activists say has devastated local Cambodian communities and ecosystems.
The new decree, issued on July 10, bars all exports of "construction sand and mud sand" from Koh Kong province to overseas but stops short of outlawing domestic sales.
It was issued in response to environmental concerns, said Meng Saktheara, a spokesman for Cambodia's mining and energy ministry.
"If we continue to allow large-scale sand dredging (in Koh Kong) for exports, it would hugely affect the natural environment and local communities," he said.
Environmental activists welcomed the move but expressed doubt it would fully halt a trade that has survived previous bans.
