Understanding Vietnam’s Maritime Zones

Vietnam’s coastline is divided into several maritime zones, each defined by international law and national legislation. Knowing the differences between these zones is essential for citizens, sailors, and policymakers.

Internal Waters vs. Territorial Sea

The primary factor that separates internal waters (nội thủy) from the territorial sea (lãnh hải) is their position relative to the baseline (đường cơ sở).

• Internal waters: Located inside the baseline. The state exercises full sovereignty, similar to its land territory. No foreign vessel has the right of innocent passage.
• Territorial sea: Extends outside the baseline up to 12 nautical miles. Foreign ships enjoy the right of innocent passage, but the coastal state retains sovereignty.

In practice, the baseline follows the low-water line along the coast. Anything inland of that line belongs to internal waters, while the sea area up to 12 nautical miles belongs to the territorial sea.

Economic Zones Beyond the Territorial Sea

Vietnam also claims two additional maritime zones that are crucial for economic development and national security:

• Contiguous Zone (Vùng tiếp giáp lãnh hải): Extends from 12 to 24 nautical miles. The state can enforce customs, fiscal, immigration, and sanitary regulations.
• Exclusive Economic Zone (Vùng đặc quyền kinh tế – EEZ): Extends up to 200 nautical miles from the baseline. Vietnam has exclusive rights to explore, exploit, conserve, and manage natural resources, both living and non‑living.

For example, a fishing vessel located 120 nautical miles from the baseline operates within the EEZ, not the territorial sea.

National Strength in the Modern Era

Vietnam’s strategic doctrine emphasizes the combination of national internal strength with the strength of the era. This concept reflects how a country can leverage its own resources while engaging with the global community.

The Decisive Role of Internal Strength

Among the factors that contribute to national power—such as foreign alliances, military capabilities, and international cooperation—the internal strength of the country is the decisive element. Internal strength includes:

• Human capital: education, health, and skilled labor.
• Economic foundation: industrial base, technology, and infrastructure.
• Social cohesion: national identity, cultural values, and political stability.

External forces can amplify these assets, but they cannot replace them. A strong internal foundation ensures that international partnerships are effective and sustainable.

Legal Responsibilities of Citizens

Vietnam’s legal framework outlines specific duties for its citizens, ranging from military service to cyber security. Understanding these obligations helps individuals avoid legal pitfalls and contributes to national security.

Conscription Age for Men

Male citizens become eligible for military registration when they reach the age of 17 years. This is the first point at which they are entered into the conscription register. The actual enlistment (ngũ) may occur later, depending on the needs of the armed forces and the individual's circumstances.

Deferral for University Students

Students enrolled in a regular university program may request a temporary deferment of the call‑up order. The law provides that a student can postpone conscription for the duration of a single academic program, ensuring that higher education is not disrupted.

Key points for students:

• Submit a formal request to the local military recruitment office.
• Provide proof of enrollment and a study plan.
• The deferment is limited to one academic cycle; after graduation, the individual must comply with the call‑up.

Cybercrime and Emerging Threats

With the rapid expansion of digital technologies, Vietnam has strengthened its legal provisions against cyber offenses. Two common crimes are identity theft and ransomware attacks.

Identity Theft (Đánh cắp danh tính)

Identity theft occurs when a person uses another individual’s personal information—such as name, ID number, or financial details—to obtain loans, open accounts, or commit fraud without permission. This crime undermines trust in financial and governmental systems.

Preventive measures include:

• Protecting personal documents and passwords.
• Monitoring credit reports regularly.
• Reporting suspicious activities to authorities promptly.

Ransomware Attacks

Ransomware is a type of malware that encrypts a victim’s data and demands a payment—usually in cryptocurrency—to restore access. The typical workflow is:

1. Malware infiltrates the system via phishing emails or malicious downloads.
2. It encrypts files, rendering them unusable.
3. The attacker displays a ransom note demanding payment for the decryption key.

Effective defenses involve regular backups, up‑to‑date security patches, and employee training to recognize phishing attempts.

Airspace Violations and International Law

Unauthorized incursions into another country’s airspace are serious violations of sovereignty. A modern example involves the use of unmanned aerial vehicles (UAVs) or drones.

Case Study: Drone Crossing the Border

When an operator pilots a drone across an international border and drops an object on the other side, the act is classified as "flying into a prohibited area and dropping objects across the border". This behavior breaches both aviation regulations and border security protocols.

Legal consequences may include:

• Criminal charges for illegal entry into sovereign airspace.
• Potential diplomatic disputes if the incident escalates.
• Financial penalties and confiscation of the UAV.

Operators should always obtain proper clearance and respect the airspace of neighboring states.

Key Takeaways for Citizens and Students

• Internal waters lie inside the baseline; the territorial sea extends up to 12 nautical miles outward.
• A vessel 120 nautical miles from the baseline operates within Vietnam’s Exclusive Economic Zone.
• The nation’s internal strength—human, economic, and social capital—is the core driver of its overall power.
• Male citizens become eligible for military registration at 17 years old; university students can defer conscription for the length of their study program.
• Identity theft involves using another person’s data for illicit gain; ransomware encrypts data and demands a ransom for decryption.
• Flying a drone into prohibited airspace and dropping objects across a border is a serious violation of international law.

By mastering these concepts, individuals can better fulfill their civic duties, protect themselves from cyber threats, and respect international norms.
