The Apricot subsea cable system — backed by Google, Meta and regional partners — is scheduled for service in 2025–2026, linking Japan, Taiwan, Guam, the Philippines, Indonesia and Singapore on routes designed to avoid single points of failure near the South China Sea. It is one of several new systems redrawing how data crosses Asia. The goal is not faster internet. It is trusted internet, routed around China.
More than 570 active and planned cables carry roughly 99% of international data traffic, with many Asia-Pacific routes funnelling through chokepoints. AI’s demand for predictable, sovereign data paths is now the force driving where the next ones get laid.
AI does not run on the cloud. It runs on glass — hair-thin fibres on the seabed, carrying laser pulses between data centres thousands of kilometres apart. Train a large model in one country and serve it in another, and the data crosses an ocean floor that almost no one defends.
That is the problem now reshaping where cables get built. Western and allied firms are not laying new lines because the old ones are slow. They are laying them because the old ones run through the wrong water.
On May 31, 2024, Australia’s Deputy Prime Minister and Defence Minister Richard Marles told a room of admirals and generals at the Shangri-La Dialogue in Singapore that “the seabed is a battlefield.” The line drew attention. The quieter story is what allied governments and US cloud giants have started building in response — a parallel map of the internet, designed to bypass Chinese-controlled waters and the narrow straits where a single anchor can sever a region’s connectivity.
The new cables avoid water, not distance
The Apricot system shows the design logic plainly. Its route between Japan and Singapore deliberately skirts the most exposed corridors of the South China Sea, threading connectivity through Guam and the Philippines instead. Google’s own project documentation frames it as resilience engineering: no single cut should isolate a country. That is a defence specification written into a commercial cable.
The vulnerability it answers is not theoretical. On February 28, 2024, at least two of the three submarine cables linking Taiwan with its outlying Matsu islands were severed, which Taiwan’s Chunghwa Telecom attributed to Chinese fishing vessels and cargo ships. Matsu residents were left on limited backup microwave links. Kuo Yu-jen, director of the Institute for National Policy Research in Taiwan, argued the repeated outages show how easily Beijing can squeeze Taiwan’s frontline islands, and called for diversified connectivity — satellite links and redundant cable routes both.
Here is the part most coverage misses. The race to build these routes is no longer led by state telecoms. It is led by US cloud hyperscalers. Google, Meta, Microsoft and Amazon are bankrolling systems including Apricot, Echo and Bifrost to harden the Japan–Southeast Asia–US corridor, while China Unicom and China Telecom push alternative routes through the Digital Silk Road. Within twelve to eighteen months, the firms that own the cables will also own the route choices — and that is where strategic control quietly shifts from governments to four companies. The open question is no longer whether cables are vulnerable. It is who gets to decide where the trusted ones go.
The internet is splitting into trusted blocs
The legal scaffolding here is thin. The 1982 UN Convention on the Law of the Sea grants the right to lay and maintain cables and obliges states to criminalise intentional damage. It leaves enforcement to national law and naval capacity. In practice, that means a cable in international water has very little protecting it beyond the goodwill of passing ships.
So the response has gone private. Cables now follow the balance sheets of cloud firms rather than the maps of telecom consortia. The vendor field tells the same story: SubCom in the US, NEC in Japan and Alcatel Submarine Networks in France build most new systems, while China’s HMN Tech faces Western sanctions and financing hurdles that keep it out of allied projects.
This is the deeper shift Marles was gesturing at. The internet was built for efficiency — the shortest path between two points. It is being rebuilt for trust, around security blocs. AI’s hunger for predictable, sovereign data flows is locking that geography in. Even if tensions ease, a cable laid to bypass China stays laid. The battlefield Marles named is not a future risk. It is the map being drawn right now.
Beyond the headline
The bigger picture
The redesign of Asia’s cable routes is part of a broader move from an open, globally integrated internet toward fragmented data spheres anchored in security blocs. As AI training and inference demand sovereign data flows, physical infrastructure is being reorganised around trusted alliances rather than pure efficiency. That locks in a more polarised digital geography, hard to unwind even if political tension fades.
The money trail
By bankrolling multi-billion-dollar systems across the Indo-Pacific, firms like Google and Meta secure privileged bandwidth for their AI workloads while steering routes away from Chinese control. This is a quiet form of industrial policy: private capital shapes strategic connectivity, and host countries compete for landing stations that bring data-centre investment and recurring capacity fees.
The reach
Asian cable disruption could ripple into domestic AI rules. If tampering in the Taiwan Strait or South China Sea exposes weaknesses in cross-border data flows, European and US regulators may speed up rules mandating local compute and storage for critical sectors. That favours firms with sovereign cloud offerings and could squeeze smaller AI providers that depend on globally distributed infrastructure.
The decisions facing companies routed through Asia
With new systems coming into service through 2026 and chokepoints still exposed, three groups need to act on this now.
- Corporate IT and risk teams
Map your exposure before assuming redundancy. Consult TeleGeography’s interactive Submarine Cable Map to see which cables carry your traffic to and from Asia-Pacific, then identify where a single chokepoint — the Luzon or Singapore Strait — sits on your critical paths.
- Compliance and policy leads at Western firms
Review the Australian Government’s Security of Critical Infrastructure framework at homeaffairs.gov.au to see how communications assets including subsea cables are classified and what obligations fall on operators. It is the clearest signal of how similar security regimes may evolve in your own jurisdiction.
- Cloud and AI infrastructure planners
Watch for G7 and Quad statements on undersea resilience expected around late-2026 defence summits. Concrete funding or joint-patrol commitments mean collective protection; vague language means you keep paying for private redundancy yourself.
Explainer
- Shangri-La Dialogue
- An annual security summit held in Singapore where defence ministers and military chiefs from across the Indo-Pacific and beyond meet. Organised by the International Institute for Strategic Studies, it has run since 2002 and serves as the region’s premier forum for defence diplomacy. The 2024 edition was the venue where Australia first elevated subsea cable protection to a stated defence priority alongside sixteen counterparts.
- Digital Silk Road
- The technology arm of China’s Belt and Road Initiative, covering telecom networks, data centres and subsea cables. Launched in 2015, it funds digital infrastructure across Asia, Africa and the Middle East, extending Chinese technical standards along the way. For subsea cables, it offers host countries an alternative to US-aligned consortia — which is precisely why allied governments now scrutinise the financing behind any new route.
