Amazon is acquiring assets, and hiring new employees in Singapore, the tech news website said, citing two sources close to the company.
There has been no official announcement by Amazon.
The report said that Amazon may debut its Prime delivery service and its AmazonFresh grocery service, perhaps as soon as early 2017.
Amazon's possible Southeast Asian foray comes soon after aggressive moves to enter India and China. In China, it started offering its Prime free-shipping service last month.
Prime gives members in the US perks like free delivery and access to a growing library of videos and music.
The US company has also pumped $3 billion(Bt105 bn) more into its Indian e-commerce operation.
