As artificial intelligence, cloud computing, and digital trade reshape the global economy, China is accelerating construction of a new kind of strategic infrastructure: undersea data highways.
This week, a major new submarine cable system known as the Asia Link Cable (ALC) officially landed in Hong Kong, marking a significant step in China’s effort to strengthen digital connectivity across Asia and reinforce its position in the emerging AI-driven economy.
Stretching roughly 6,100 kilometers, the cable links Hong Kong, Hainan, Singapore, Vietnam, the Philippines, Malaysia, and Brunei — connecting some of Asia’s fastest-growing digital markets through a high-capacity data network designed for the next generation of internet traffic.
While undersea cables rarely attract public attention, they form one of the most critical foundations of the modern global economy.
According to the International Telecommunication Union, about 99 percent of international internet traffic travels through submarine cables. Everything from financial transactions and cloud services to video streaming, AI computing, and cross-border communications depends on these invisible digital corridors beneath the ocean.
In many ways, they have become the geopolitical infrastructure of the digital age.
The Infrastructure Behind the AI Economy
The timing of the project reflects a broader transformation underway in China’s economy.
As artificial intelligence adoption accelerates, demand for data transmission and computing coordination is exploding. Chinese officials say daily AI token usage surged from just over 1 trillion at the beginning of 2025 to around 100 trillion by the end of the year, before climbing even higher in early 2026.
That rapid growth is turning data infrastructure into a strategic national priority.
China Unicom, one of the companies involved in the project, said the new cable system is designed to support large-scale cross-border AI applications, including real-time computing coordination and cross-border AI inference.
The company claims the cable can transmit more than 80 billion AI tokens per second — a figure that illustrates how modern submarine cables are evolving beyond traditional internet traffic into core infrastructure for the AI economy.
This is not simply about faster downloads or smoother video calls.
It is about enabling massive flows of data between cloud servers, AI training centers, financial systems, industrial platforms, and digital services spread across multiple countries.
In the age of artificial intelligence, connectivity itself is becoming an economic asset.
Why Southeast Asia Matters
The cable’s geographic focus is also significant.
Southeast Asia has emerged as one of the world’s fastest-growing digital regions, fueled by rising internet penetration, expanding e-commerce markets, rapid cloud adoption, and increasing demand for AI services.
For China, strengthening digital links with Southeast Asia serves both economic and strategic goals.
Economically, it deepens integration with neighboring markets that are becoming increasingly important to China’s trade and technology sectors. Strategically, it helps reinforce China’s role in regional digital infrastructure at a time when global technology competition is intensifying.
The project also strengthens Hainan’s ambitions to become a major international digital hub.
Officials said the cable system will significantly reduce network latency between Hainan and Southeast Asia, creating faster connections for industries such as finance, international trade, cross-border e-commerce, and digital services.
That matters because in sectors driven by AI, finance, and cloud computing, even milliseconds can have commercial value.
The New Competition Beneath the Ocean
Submarine cables are increasingly becoming part of global geopolitical competition.
For decades, these networks were viewed mainly as technical infrastructure built quietly by telecom operators. Today, governments see them as critical assets tied to economic security, technological influence, and digital sovereignty.
The United States, China, Europe, and regional powers are all racing to secure control over data routes, cloud infrastructure, and next-generation communications systems.
As AI systems become more data-intensive, the importance of high-speed international connectivity will only grow.
That is one reason China is investing heavily not only in AI models and semiconductor capabilities, but also in the physical infrastructure required to move and process enormous volumes of information across borders.
The Asia Link Cable reflects this broader strategy.
It combines telecommunications, cloud computing, AI infrastructure, and regional economic integration into a single project — effectively creating a new digital artery connecting China to the wider Asian economy.
Beyond Trade: Building the Digital Economy
For global businesses, projects like the ALC signal how economic competition is increasingly shifting from traditional trade routes toward digital infrastructure networks.
Just as ports, railways, and shipping lanes defined earlier eras of globalization, undersea cables are becoming the backbone of the next phase of economic integration.
Countries that control faster, larger, and more resilient digital networks may gain significant advantages in AI development, cloud services, fintech, advanced manufacturing, and cross-border digital trade.
China appears determined to be at the center of that transformation.
The landing of the Asia Link Cable is therefore more than a telecommunications milestone. It is part of a much larger effort to build the infrastructure for a future economy powered not only by goods and manufacturing, but by data, algorithms, and real-time global connectivity.
