Oil is one of the resources that China requires and will require in a big way to sustain its growth.
It is critical to China's industrial and military existence.
Apart from the pipelines to Xinjiang from CAR, the pipeline from Gwadar to Xinjiang through POK and the pipeline from Myanmar to China, to feed its insatiable thirst for oil, it will also require that Straits of Hormuz and Straits of Malacca free from any crisis.
Therefore, the Indian Ocean takes great relevance for China strategically.
While China is going hard at increasing her naval fleet to be reckonable in the South China Sea, Singpore and Indonesia alone can guarantee her naval access into the Indian Ocean.
Therefore, Indonesia and Singapore will become a hub of interest for China.
It will also be for the US to ensure that the Chinese naval might is kept on a tight leash and not allowed unhindered access into the Indian Ocean, strategically speaking.
An interesting scenario develops in the strategic realm.
