Indonesia boosts military presence near Australia and ramps up efforts to increase its firepower | News.com.au Indonesia sends warships to patrol southern border | World news | theguardian.com TNI gears up, sets sights on foreign threats | The Jakarta Post This, on top of the earlier Indonesia-Australia spying row, is a godsend to Chinese strategic planners, since it is a long-term irritant with lots of national pride at stake. My sources tell me those radar systems watching Australia were built with Chinese assistance. Think of it as a Chinese '---- you too' to America's radar stations in Taiwan, Korea, and Japan. The other thing to note is that Indonesia has over half a dozen other straits with enough water depth to substitute for Malacca, and yet enough shallow water in between each to make ASW easy relative to the open waters of the Pacific. This means if China gets Indonesia on its side, China's shipping can make it home safely through the Indonesian archipelago even if Malacca is blockaded.
