China Unicom launches new Hong Kong-Cambodia cable link as mainland firms leverage city
The project ties a high-speed data and information corridor running through Southeast Asia with Hong Kong

A new state-of-the-art submarine cable, which will enable faster internet for Cambodia, made a successful landing in Hong Kong earlier this week, another milestone in a series of projects undertaken by Chinese firms to bolster information infrastructure by laying and expanding international seabed networks.
The project, named SHV-HK, links Sihanoukville, a coastal port city in Cambodia, to Hong Kong, traversing 3,000 kilometres through the Gulf of Thailand, the southern tip of Vietnam and the vast South China Sea before reaching the Tseung Kwan O landing station in Hong Kong. Its investor is state-owned telecommunications giant China Unicom.
“The linkage forms part of China-Cambodia cooperation in digital infrastructure under Beijing’s Belt and Road Initiative,” the telecoms firm said in a statement. It said it would aim to significantly strengthen overseas internet connection for Cambodia’s 17.3 million people and address gaps in the country’s digital development.
The project also forms a synergy with the land-based China-Laos-Cambodia data links and adds more resilience to Cambodia’s overseas internet connectivity, securing data transmission and communications between China and members of the Association of Southeast Asian Nations (Asean).
Leading Chinese firms in technology and telecoms have engaged in a flurry of investment in new data centres, as well as land and submarine cables, to expand computing capacity. Finance, artificial intelligence, biomedicine and autonomous driving all rely on high-performance computing.
