A. Project Background

1. The Asian Development Bank (ADB) approved a loan worth 150 million USD in December 2017 to help improve economic connectivity and improve living standards for the four Northeastern provinces of Vietnam through strengthening infrastructure facilities and basic services. This support is expected to benefit more than 212,000 people. The project closing date is 30 September 2023.

2. The four project provinces including Bac Kan, Cao Bang, Ha Giang and Lang Son all have considerable potential to become commercial nodes thanks to the strategic position in the trade network between China, Hanoi, Hai Phong port and the Greater Mekong Sub-region North-South Economic Corridor funded by ADB. However, these potentials have not been fully developed, with the average gross domestic product per capita of the four provinces in 2015 reaching only USD 1,160, approximately half of the national average of USD 2,036.

3. The Basic Infrastructure for Inclusive Growth in the Northeastern Provinces Sector Project will help remove barriers through the development of basic infrastructure in key fields including trade, transport, health service and agriculture.

4. Specifically, the project will help improve road connectivity between provinces by upgrading about 121km of provincial roads and 144km of district roads, rural water supply for about 42,300 people, and improving Agricultural and Rural Value Chain infrastructure in Lang Son province through connections from farm-to-market and support for local businesses. The project will also strengthen the capacity of provincial governments, particularly on public property management.

5. The project has four outputs: (i) Output 1: Road network connectivity improved; (ii) Output 2: Rural water supply improved; (iii) Output 3: Agriculture and Rural Values Chain infrastructure (ARVC) in Lang Son province improved; (iv) Output 4: Decentralized Public Asset Management Processes Established.

6. Cao Bang is one of 4 provinces participating in the project. For more details, please see the information in the Report and Recommendations to the President, at link: https://www.adb.org/sites/default/files/project-documents/49026/49026-002-rrp-en.pdf, Project Administration Manual-PAM, at link: https://www.adb.org/sites/default/files/projectdocuments/49026/49026-002-pam-en.pdf.
