Tong Fuk is a village located on Lantau Island in Hong Kong, China, situated along the southern coastline of the island. Despite its modest scale as a settlement, Tong Fuk serves as a submarine cable landing point, hosting one international submarine cable that connects China to other economies across the North Asia region. Its coastal position on South Lantau has made it a viable terminus for undersea infrastructure serving the broader Hong Kong and Pearl River Delta corridor.
The single cable landing at Tong Fuk links China directly to Japan, South Korea, and Taiwan, establishing a regional loop across the East Asian maritime corridor. This configuration supports inter-country connectivity within Northeast Asia, spanning the South China Sea and East China Sea routes that tie together some of the region's most active digital economies.
FLAG North Asia Loop / REACH North Asia Loop is the submarine cable landing at Tong Fuk. Measuring 9,504 kilometres in total length, the system reached ready-for-service status in 2001. In addition to Tong Fuk in China, the cable connects to landing points in Japan, South Korea, and Taiwan, forming a loop topology across the North Asian region. The cable's name reflects its operational history under two associated entities — FLAG and REACH — serving as a looped system designed to provide resilience across the Northeast Asian submarine cable network.
Within China's submarine cable infrastructure, which spans 24 cables across 24 landing points, Tong Fuk hosts one cable, placing it among the smaller landing points in the country by cable count. Larger hubs such as Chung Hom Kok and Tseung Kwan O each host six cables, while Chongming and Nanhui each host four, and Shantou hosts three. Lantau Island as a whole accommodates two cable landings across its various coastal access points, with Tong Fuk contributing one of those connections.
Tong Fuk functions as a single-cable terminus rather than a multi-cable hub, serving as the Chinese endpoint of the FLAG North Asia Loop / REACH North Asia Loop system. Through this cable, Tong Fuk participates in a regional loop connecting China, Japan, South Korea, and Taiwan — four of Northeast Asia's most significant economies in terms of internet traffic exchange. The loop architecture of the cable provides an inherent degree of path redundancy compared to linear point-to-point systems.
While Tong Fuk does not concentrate the volume of cables found at larger Chinese landing points, its role in the North Asia loop ensures that it remains a named node in the Northeast Asian submarine cable graph, contributing to the distributed structure of China's overall submarine cable footprint along the South Lantau coastline.
