Mao made the remarks at a regular press briefing when asked to comment on the latest progress in constructing the high-speed line.
The joint commissioning and testing of the Jakarta-Bandung HSR started on Monday, conducted before the opening of the high-speed railway to ensure the safe and smooth operation of the trainsets, marking a milestone in the construction of the railway project.
Mao said the Jakarta-Bandung HSR is the first overseas high-speed railway project that fully uses Chinese railway systems, technology, and industrial components, a flagship project of China-Indonesia Belt and Road cooperation.
Noting that the Jakarta-Bandung HSR will be the first high-speed railway in Indonesia and Southeast Asia, Mao said the project entered the sprint stage.
Mao said with the joint efforts of the two countries, the Jakarta-Bandung HSR will be completed and opened to traffic as scheduled, paving the way for the well-being of local people and accelerating the development of Indonesia and the region.
