An energy analyst said exploring for oil and gas near disputed islands in the South China Sea is too much of a gamble for international energy companies because of the tensions in the region and unconfirmed estimates of the size of the oil and gas deposits.
China has been reclaiming land and building port and military facilities on disputed islands and reefs in the South China Sea, which stretches from Singapore to Taiwan.
