In addition to ensuring maritime safety in the surrounding territorial waters, lighthouses on islands of Truong Sa (Spratly) archipelago in Truong Sa district of the south central province of Khanh Hoa, have also affirmed Vietnam's sovereignty over seas and islands.
46 years after national reunification, Truong Sa (Spratly) archipelago has been given a facelift. The archipelago is covered by not only the blue of the sea but also the green of trees planted by soldiers. On the islands of Song Tu Tay, Son Ca, Nam Yet and Sinh Ton, four trees, aged more 300 years old, have been recognised as "Vietnamese Heritage Trees".
For naval soldiers in Truong Sa (Spratly) island district, Khanh Hoa province, 'island is home and sea is homeland'. They share the same will, solidarity, creativity in production and readiness for combat, determining to protect the country's sacred sovereignty over seas and islands.
The fluttering sacred national flag is a motivation for soldiers stationed on remote islands to firmly safeguard the country’s sea and islands and territorial integrity.
