The city hosted a conference attended by around 1,000-1,200 participants, including between 580 and 780 domestic and foreign investors and corporate representatives.

During the event, Hanoi granted in-principle approvals and investment registration certificates for projects across the city, while signing memoranda of understanding with domestic and international corporations and economic organizations.

The city also launched a public exhibition showcasing the master plan, featuring scale models, 3D mapping technology, videos and planning maps illustrating Hanoi's future spatial development.

A separate exhibition at the Hanoi Museum will remain open to residents and businesses, displaying the master plan through large-scale models, planning documents and multimedia presentations.

The exhibition includes a 7-meter-diameter master plan model incorporating the city's latest planning boundaries, a 1,200-square-metre gallery using 3D projection mapping to present future development scenarios, and displays tracing Hanoi's urban expansion, land-use planning and infrastructure development over time.

The museum also features architectural models of selected flagship projects, documentary films and a pilot digital planning information system allowing visitors to explore the city's development plans.

Speaking during preparations for the event on Sunday, Hanoi People's Committee Chairman Vu Dai Thang described the conference as more than a conventional investment promotion event, saying it marked the beginning of a new stage in the capital's development.

He said it was the first large-scale investment promotion conference held by Hanoi in many years and the first to take place under a new policy framework that includes resolutions issued by the Communist Party's central leadership, the 2026 Capital Law and the newly announced 100-year master plan.

"The significance of this conference goes beyond investment promotion," Thang said. "It represents an important milestone in Hanoi's socio-economic development."

Tran Quang Tuyen, deputy director of Hanoi's Department of Planning and Architecture, said the master plan should be viewed as a strategic framework rather than a detailed implementation blueprint.

He said the plan establishes broad spatial development directions, including growth zones, major urban centers, economic development corridors, strategic transport infrastructure and the overall framework for urban and rural development.

Detailed planning, land-use zoning and individual construction projects will be developed during subsequent district-level planning and project implementation stages, he added.
