TOKYO -- Japanese trading house Mitsubishi Corp. will partner with Singapore's state-backed investor Temasek Holdings to build a high-tech community near Indonesia's capital, Nikkei has learned. The pair have formed a joint venture for the project, which will span about 1 sq. km in Bumi Serpong Damai, a planned city about 25 km southwest of Jakarta. Local developer Sinar Mas Land will participate as well. The move marks Mitsubishi's first full-fledged smart city project and comes as Southeast Asia embraces the integration of technology into urban development.
