The US-made proposals to Indonesian defence and foreign ministers in July and August before approaching Indonesian President Joko Widodo, who rejected the request, according to Reuters.
Indonesian officials told the news agency that Jakarta decided to stay true to its neutral foreign policy amid the US-China tensions over regional influence.
In September, Indonesian Foreign Minister Retno Marsudi said that Jakarta does not want "to get trapped by this rivalry".
The news agency noted that the US-made P-8 Poseidon maritime surveillance planes are crucial in monitoring China’s military activities in the South China Sea amid tensions between Beijing and its regional neighbours over the control of resource-rich waters. Indonesia also considers parts of the South China Sea as its own. Washington views the sea as an international waterway and routinely defies China with surveillance flights, and patrols by US warships.
Recently, the US blacklisted 24 Chinese companies, saying that they are helping the ruling Chinese Communist Party construct artificial islands in the South China Sea, which the US sees as a military provocation.
