JAKARTA: Indonesia has warned that its coal supply situation remains critical, ahead of Wednesday's review of its export ban, unnerving global markets for the fuel used to generate most of the electricity that drives Asia's biggest economies.
Coal futures in China, the world's biggest consumer of the fuel, surged on Tuesday after Indonesia, the top exporter of the coal used in power plants and China's largest overseas supplier, on Saturday banned exports for January to avoid outages at the generators run by state-owned utility Perusahan Listrik Negara (PLN).
