Indonesia is targeting a revamp of its Batam island region to draw in $60bn of investment as an alternative shipping and manufacturing hub to Singapore.
The free-trade zone has already attracted about $20bn since 2007.
Authorities want to reclaim about 8,000 hectares of unused or confiscated land, Intellasia reported.
“We aim to develop enclaves of special economic zones in Batam,” said Edy Putra Irawady, acting head of Batam Indonesia Free Trade Zone Authority.
