In April 2015, the People's Republic of China competed with Japan when the two countries offered their high-speed trains to Indonesia.

On 6 October, the formation of the consortium was reported to the Financial Services Authority, and President Joko Widodo passed Presidential Regulation (Perpres) No.

The company was formed on 16 October 2015 and is planned to prioritise commercialisation, not burden the state budget, and promote synergies between businesses.
