Nha Trang is a coastal city in Vietnam, serving as the capital of Khánh Hòa Province. Located on the South Central Coast, it is renowned for its picturesque beaches with fine white sand and clear ocean waters, making it a major tourist destination. The city also serves as a significant center for marine science, home to the Nha Trang Oceanography Institute and the Hon Mun marine protected area, recognized globally by IUCN [1].

Historically, Nha Trang was known as Kauthara under the Champa Kingdom, with the ancient Po Nagar Towers still standing as a testament to its rich past. Over centuries, it transitioned from a deserted area to a French-influenced townlet and eventually a provincial city of Vietnam in 1977. Its development into a modern urban center has been marked by significant urbanization and infrastructure projects, while retaining its natural beauty and cultural heritage [1].

Nha Trang operates as a provincial city (Class-1) within the Socialist Republic of Vietnam. The national government is a socialist republic governed by the Communist Party of Vietnam, which holds significant leadership in shaping national policies and socio-economic development [3, 4]. At the local level, Nha Trang is administered through a People's Committee, led by a President and Vice Presidents. The city is further subdivided into 22 wards and communes, comprising 14 urban wards and 8 suburban communes [1]. This administrative structure, aligning with the broader state apparatus from central to grassroots levels, ensures the implementation of Party guidelines and state laws [4].

Nha Trang's economy is primarily driven by tourism, leveraging its pristine beaches, clear waters, and mild climate, which attract a large number of international and domestic visitors. This has led to the development of numerous resorts, amusement parks, and related services. Beyond tourism, the city's suburban areas have seen significant growth in the shipbuilding industry, contributing substantially to the local economy. Fishery, particularly lobster farming, also plays a vital role. Khánh Hòa Province, with Nha Trang as its capital, is a significant contributor to Vietnam's national budget revenues, indicating a robust local economy with diverse sectors [1].

Nha Trang's infrastructure supports its role as a major tourist and economic hub. The city is well-connected by National Route 1, a vital north-south road, and the Reunification Railway, with a station in Nha Trang. While Cam Ranh International Airport, located 28 km south, serves as the main civilian airport, connecting Nha Trang domestically and internationally, there are ongoing developments like the deep-water port project in Vân Phong Bay designed to handle large cargo volumes and boost regional economic activity. The city also features extensive resort infrastructure, including the Vinpearl Cable Car connecting to Hon Tre Island, enhancing its tourism appeal [1].
