Deputy Minister of Planning and Investment Tran Quoc Phuong stated that, based on initial assessments, the high-speed rail project is the largest-scale project to date, with an estimated total investment of nearly $70 billion. If this amount is invested from now until 2035, the project's impact is expected to increase GDP by approximately 0.97 percentage points. Additionally, this project will have a direct impact on 7-8 sectors.
