evidence: In June 2014, drivers crossing the causeway between Singapore and Johor, Malaysia, began to notice something strange. A slender sandbar, which had long stood in the middle of the narrow straits, had started to grow, and was slowly inching toward Singapore. Construction vehicles had arrived, and small barges passed continuously, dumping load after load of sand into the water. Newspapers soon reported that this expanding mound was to become the site of Forest City, a 2,000-hectare high-rise housing development jutting out from the Malaysian port of Tanjung Pelepas. As this privately funded project crept toward Singapore’s national border, the security state doubtlessly felt violated. In response, Prime Minister Lee Hsien Loong requested that the Malaysian government halt work on the project, and threatened to file a complaint with the International Tribunal for the Law of the Sea in Hamburg.
