The coast guard does not belong to any service.

The coast guard does not belong to arms other than the navy.

The Chinese People's Liberation Army Navy Coast Guard is a branch of the People's Navy, including coastal artillery units, shore-to-ship missile units, anti-aircraft artillery units and ground-to-air missile units. Carry out coastal defense operations, resist enemy attacks on naval bases, airports, ports, anchorages and important coasts, guard straits, waterways and air routes, cover coastal maritime traffic lines and their own ships, and support garrison operations and national air defense on islands and important places.

China Marine Police defended China's sovereignty and dignity at the most critical moment in New China, and became the strongest first line of defense for China's maritime defense during the weak navy. Today, China's navy has made great progress. China navy gradually moved from offshore to blue ocean, becoming the new first line of defense at sea in China, followed by the second line of defense composed of marine police, and the coastal defense forces became the last line of defense.

Significance of coastal defense forces

1, safeguarding national security and territorial integrity

The coast is one of the important national defense lines, and any threats and attacks from the sea may pose a threat to national security and territorial integrity. Strengthening coastal defense can effectively prevent threats such as maritime piracy and illegal immigration and safeguard national security and territorial integrity.

2. Protection of marine resources and environment

Marine resources are very important to national economic development and people's lives. Coastal defense can maintain the safety and stability of marine resources, prevent illegal fishing, pollution and destruction activities, and maintain the balance and stability of marine ecological environment.

3. Maintain the safety of maritime navigation.

Coastal defense can not only protect the safety of national maritime navigation and transportation, but also ensure the safety of international trade and ports. When sailing at sea, ships and goods often encounter risks such as piracy, bad weather and maritime accidents. Strengthening coastal defense can effectively reduce these risks and improve the safety and stability of maritime navigation.
