海南省西沙群島、南沙群島、中沙群島弁事処

This administration office in Hainan Province manages governmental affairs for three major island groups in the South China Sea: the Paracel, Spratly, and Macclesfield islands. It coordinates maritime activities, resource exploration, and administrative matters across these marine territories.

The office was established to oversee marine territories marked by a nine-dash boundary line with origins dating to 1947 during the Republic of China period. This early territorial definition laid the groundwork for the current administrative framework.

This office represents Chinese governmental presence in the South China Sea and serves as the administrative center for island communities in the region. It embodies state authority over the waters and the people living across these territories.

The office is accessible through Hainan Province and primarily serves to coordinate administrative tasks for government officials and authorized personnel. Visitors should be aware this is a government facility with restricted public access.

The office manages claims to one of the most extensive marine territories in the South China Sea, with administrative jurisdiction spanning multiple disputed island archipelagos. This management role makes it one of Asia's most complex maritime administrative structures.
