(Chinhphu.vn) - The Government has just issued Decree No. 278/2025/ND-CP dated October 22, 2025, regulating the mandatory connection and sharing of data between agencies in the political system.

By December 31, 2026 at the latest, the mandatory connection and sharing of data between agencies within the political system will be implemented uniformly through the Data Sharing and Coordination Platform.

The Decree, comprising 5 chapters and 25 articles, regulates mandatory data sharing and connectivity activities between agencies within the political system from the central to local levels, ensuring the readiness for data connection and sharing; the national data architecture framework, the national data governance and management framework, and a shared data dictionary.

This Decree applies to ministries, ministerial-level agencies, government agencies, central agencies of political organizations, the Supreme People's Procuracy , the Supreme People's Court, the State Audit Office, the Office of the President, the Office of the National Assembly, central agencies of the Vietnam Fatherland Front, People's Committees at all levels (hereinafter referred to as ministries, central agencies, and localities), agencies, organizations, and individuals involved in activities directly or related to connecting and sharing data between databases and the National Data Architecture Framework, the National Data Governance and Management Framework, and the Common Data Dictionary.

Integrating, synchronizing, and utilizing national master data is mandatory for agencies and organizations within the political system when building, updating, or operating databases and information systems.

The source of national master data is established or initiated on the principle of a single, trusted data source. A piece of data has only one reliable source.

Master data is established or initialized from a set of identification keys. The Minister of Public Security publishes the national master data catalog on the shared data dictionary system, based on agreement with agencies within the political system.

The Ministry of Public Security issues key identifiers for master data and builds, manages, operates, and updates the national master data catalog, ensuring accuracy, consistency, and technical interoperability.

Regarding specialized master data (which is master data that is connected, shared, exploited, and used internally within Party and State agencies, the Vietnam Fatherland Front Committee, and political and social organizations), the Decree stipulates that ministries and central agencies are responsible for identifying, publishing, and updating their specialized master data sets and integrating them into the Common Data Dictionary System.

The Data Sharing and Coordination Platform performs authentication and authorization for data exchange between the two parties. (Data sharing connection on demand);

b) The information system of the data-sharing agency synchronizes part or all of its data with the information system of the data-using and exploiting agency through the Data Sharing and Coordination Platform;

c) The information system of the data-sharing agency synchronizes data to the National Integrated Database through the Data Sharing and Coordination Platform to facilitate coordination for agencies using and exploiting the data;

d) Sharing data that is packaged and stored on information storage media.

c) Forms of data connection and sharing, and other databases of ministries, departments, and localities directly connect to the Data Sharing and Coordination Platform through Agent Nodes located at ministries, departments, and localities;

d) The Agent Node establishes a connection with the data sharing and coordination platform located at ministries, departments, and localities, which is set up, configured, and installed by the National Data Center.
