Finance daily Bisnis Indonesia reported that the project's investors — including film studio and park operator Universal Studios – are expected to break ground for the 100-hectare theme park in September, citing Boyolali district head Seno Samudro.
The Jakarta Globe is still awaiting confirmation from The Walt Disney Company and Universal Studios about the project's start date.
If the plan comes to fruition, Boyolali will be host to Asia's fourth Disney theme park, after Hong Kong, Shanghai and Tokyo.
However, previous proposals for a Disney park in the country have stalled in recent years.
In 2014, state-owned airport operator Angkasa Pura II said it would study the feasibility of building a theme park near the company's international airport in Kuala Namu, North Sumatra.
A year later, rumors emerged that MNC Land – the property developer company of media mogul Hary Tanoesoedibjo – would build a Disneyland theme park in resort areas in Lido, West Java.
However, the company later clarified that Disney is not affiliated with the upcoming Lido park.
