Turf war -Disappearing islands? Singapore and Indonesia at odds

As reported in Singapore accused of land grab as islands disappear by boatload:

With more than 17,000 islands — from the jungly expanses of Borneo and Sumatra to unnamed rocks jutting out of the sea — you may think that Indonesia would not mind if a few of them went missing. But the huge South-East Asian nation has become caught up in a furious dispute with Singapore, its tiny neighbour, which is accused of literally making off with its territory.

Indonesia has banned the export of sand and imposed strict controls on shipments of gravel, after fears that its islands were being loaded on to ships and carried away to Singapore. In its thirst for building materials and landfill to reclaim new territory from the sea, Indonesians allege, Singapore has been stealing the land beneath their feet.

The dispute reached a climax this week after 24 tugs and barges, carrying granite chips, were intercepted by the Indonesian authorities as they sailed home to Singapore. Jakarta announced that future exports would be allowed only if the granite could be certified as environmentally friendly.

“Some of these islands are reduced to islets, and could even disappear below the surface,” Hendropriyono, Indonesia’s former intelligence chief, has said. “This could theoretically lead to a cartographic zero-sum game in which Singapore’s gain could be at Indonesia’s territorial loss.”
