US v. China: The Slow and Sure Conquest of Internet Infrastructure


A new front has opened in the battle between the U.S. and China over control of global networks that deliver the internet. This one is beneath the ocean. While the U.S. wages a high-profile campaign to exclude China’s Huawei Technologies Co. from next-generation mobile networks over fears of espionage, the company is embedding itself into undersea cable networks that ferry nearly all of the world’s internet data.

About 380 active submarine cables—bundles of fiber-optic lines that travel oceans on the seabed—carry about 95% of intercontinental voice and data traffic, making them critical for the economies and national security of most countries. 

The Huawei Marine’s Undersea Cable Network majority owned by Huawei Technologies, has worked on some 90 projects to build or upgrade submarine cables around the world…US o fficials say the company’s knowledge of and access to undersea cables could allow China to attach devices that divert or monitor data traffic—or, in a conflict, to sever links to entire nations.  Such interference could be done remotely, via Huawei network management software and other equipment at coastal landing stations, where submarine cables join land-based networks, these officials say.

Huawei Marine said in an email that no customer, industry player or government has directly raised security concerns about its products and operations.Joe Kelly, a Huawei spokesman, said the company is privately owned and has never been asked by any government to do anything that would jeopardize its customers or business. “If asked to do so,” he said, “we would refuse.”

The U.S. has sought to block Huawei from its own telecom infrastructure, including undersea cables, since at least 2012. American concerns about subsea links have since deepened—and spread to allies—as China moves to erode U.S. dominance of the world’s internet infrastructure…..Undersea cables are owned mainly by telecom operators and, in recent years, by such content providers as Facebook and Google. Smaller players rent bandwidth.Most users can’t control which cable systems carry their data between continents. A handful of switches typically route traffic along the path considered best, based on available capacity and agreements between cable operators.

In June 2017, Nick Warner, then head of Australia’s Secret Intelligence Service, traveled to the Solomon Islands, a strategically located South Pacific archipelago. His mission, according to people familiar with the visit, was to block a 2016 deal with Huawei Marine to build a 2,500-mile cable connecting Sydney to the Solomons.  Mr. Warner told the Solomons’ prime minister the deal would give China a connection to Australia’s internet grid through a Sydney landing point, creating a cyber risk, these people said. Australia later announced it would finance the cable link and steered the contract to an Australian company.  In another recent clash, the U.S., Australia and Japan tried unsuccessfully in September 2018 to quash an undersea-cable deal between Huawei Marine and Papua New Guinea.

U.S. and allied officials point to China’s record of cyber intrusions, growing Communist Party influence inside Chinese firms and a recent Chinese law requiring companies to assist intelligence operations. Landing stations are more exposed in poorer countries where cyber defenses tend to be weakest, U.S. and allied officials said. And network management systems are generally operated using computer servers at risk of cyber intrusion. Undersea cables are vulnerable, officials said, because large segments lie in international waters, where physical tampering can go undetected. At least one U.S. submarine can hack into seabed cables, defense experts said. In 2013, former National Security Agency contractor Edward Snowden alleged that Britain and the U.S. monitored submarine cable data. The U.S. and its allies now fear such tactics could be used against them. American and British military commanders warned recently that Russian submarines were operating near undersea cables. In 2018, the U.S. sanctioned a Russian company for supplying Russian spies with diving equipment to help tap seabed cables.

China seeks to build a Digital Silk Road, including undersea cables, terrestrial and satellite links, as part of its Belt and Road plan to finance a new global infrastructure network. Chinese government strategy papers on the Digital Silk Road cite the importance of undersea cables, as well as Huawei’s role in them. A research institute attached to China’s Ministry of Industry and Information Technology, in a paper published in September, praised Huawei’s technical prowess in undersea cable transmission and said China was poised to become “one of the world’s most important international submarine cable communication centers within a decade or two.” China’s foreign and technology ministries didn’t respond to requests for comment…

Huawei Marine Networks

Bjarni Thorvardarson, then chief executive of the cable’s Ireland-based operator, said U.S. authorities raised no objections until 2012, when a congressional report declared Huawei Technologies a national security threat. Mr. Thorvardarson wasn’t convinced. “It was camouflaged as a security risk, but it was mostly about a preference for using U.S. technology,” he said. Under pressure, Mr. Thorvardarson dropped Huawei Marine from Project Express in 2013. The older cable network continued to use Huawei equipment.

The company is now the fourth-biggest player in an industry long dominated by U.S.-based SubCom and Finnish-owned Alcatel Submarine Networks. Japan’s NEC Corp is in third place.Huawei Marine is expected to complete 28 cables between 2015 and 2020—nearly a quarter of all those built globally—and it has upgraded many more, according to TeleGeography, a research company.

The Expoitation of Seabed

Patania One became in May 217the first robot in 40 years to be lowered to the sea floor in the Clarion Clipperton Zone (CCZ), about 5,000 metres beneath the Pacific ocean…There it gathered data about the seabed and how larger robots might move carefully across it, sucking up valuable minerals en route.

The CCZ is a 6m square-kilometre (2.3m square-mile) tract between two of the long, straight “fracture zones” which the stresses of plate tectonics have created in the crust beneath the Pacific. Scattered across it are trillions of fist-sized mineral nodules, each the result of tens of millions of years of slow agglomeration around a core of bone, shell or rock. Such nodules are quite common in the Pacific, but the CCZ is the only part of the basin where the International Seabed Authority (ISA), which regulates such matters beyond the Exclusive Economic Zones (EEZs) of individual countries, currently permits exploration. Companies from Japan, Russia, China and a couple of dozen other countries have been granted concessions to explore for minerals in the CCZ. The ISA is expected to approve the first actual mining in 2019 or 2020.

This could be big business. James Hein of the United States Geological Survey and colleagues estimated in a paper in 2012 that the CCZ holds more nickel, cobalt and manganese than all known terrestrial deposits of those metals put together. The World Bank expects the battery industry’s demand for these, and other, minerals to increase if the transition to clean energy speeds up enough to keep global temperatures below the limits set in the Paris agreement on climate.

One of the firms attracted by this vast potential market is DEME, a Belgian dredging company ….Korea, Japan and China all have state-run research projects looking to dredge nodules from the deep sea with robots: “It really is a race,” says Kris Van Nijen, who runs DEME’s deep-sea mining efforts…

[It was expected]that deep-sea mining would develop rapidly by the 1980s. A lack of demand (and thus investment), technological capacity and appropriate regulation kept that from happening. The UN Convention on the Law of the Sea (UNCLOS), which set up the ISA, was not signed until 1982. (America has still not ratified it, and thus cannot apply to the ISA for sea-floor-mining permits.)

Mr Van Nijen and his competitors think that now, at last, the time is right. DEME is currently building Patania Two, or P2… In order to satisfy the ISA, this new machine does not just have to show it can harvest nodules; it also has to show that it can do so in an environmentally sensitive way. Its harvesting will throw up plumes of silt which, in settling, could swamp the sea floor’s delicate ecosystem. A survey of CCZ life in 2016 found a surprising diversity of life. Of the 12 animal species collected, seven were new to science…

The CCZ is not the only sea floor that has found itself in miners’ sights. Nautilus, a Canadian firm, says it will soon start mining the seabed in Papua New Guinea’s EEZ for gold and copper, though at the time of writing the ship it had commissioned for the purpose sits unfinished in a Chinese yard. A Saudi Arabian firm called Manafai wants to mine the bed of the Red Sea, which is rich in metals from zinc to gold. There are projects to mine iron sands off the coast of New Zealand and manganese crusts off the coast of Japan. De Beers already mines a significant proportion of its diamonds from the sea floor off the coast of Namibia, although in just 150 metres of water this is far less of a technical challenge.

If the various precautions work out, the benefits of deep-sea mining might be felt above the water as well. Mining minerals on land can require clearing away forests and other ecosystems in order to gain access, and moving hundreds of millions of tonnes of rock to get down to the ores. Local and indigenous people have often come out poorly from the deals made between miners and governments. Deep-sea mining will probably produce lower grade ores, but it will do so without affecting human populations.

The Power of Data Pipelines: google, facebook and co.

The ships that lay electronic cables across the ocean floor look like cargo vessels with a giant fishing reel on one end. They move ponderously across the open water, lowering insulated wire into shallow trenches in the seabed as they go. This low-tech process hasn’t changed much since 1866, when the SS Great Eastern laid the first reliable trans-Atlantic telegraph cable, capable of transmitting eight words per minute. These days, the cables are made of optical fiber, can carry 100 terabits of data or more in a second, and aren’t owned only by telephone companies.

Among the newcomers are a few of the world’s leading internet companies, which have concluded that, given the cost of renting bandwidth, they may as well make their own connections. Facebook and Microsoft have joined with Spanish broadband provider Telefónica to lay a private trans-Atlantic fiber cable known as Marea. The three companies will divide up the cable’s eight fiber strands, with Facebook and Microsoft each getting two. The project, slated to be completed by the end of 2017, marks the first time Facebook has taken an active role in building a cable, rather than investing in existing projects or routing data through pipes controlled by traditional carriers. Marea will be Microsoft’s second private cable; a trans-Pacific one is scheduled to come online in 2017.

In June 2016, Google said it had finished a data pipeline running from Oregon to Taiwan, and it has at least two more coming: one from the U.S. to Brazil; the other, a joint project with Facebook, will connect Los Angeles and Hong Kong. Amazon.com made its first cable investment in May, announcing plans for a link between Australia and New Zealand and the U.S. Worldwide, 33 cable projects worth an estimated $8.1 billion are scheduled to be online by 2018, according to TeleGeography. That’s up from $1.6 billion worth of cables in the previous three years. And bandwidth demand is expected to double every two years. ..

Cables are just one way to increase the supply of bandwidth and cut costs, says Chetan Sharma, an analyst and telecom consultant. Facebook is also working on satellites, lasers, and drones to deliver internet access to remote places, and Google has experimented with hot air balloons. So far, undersea cables remain the best option for crossing oceans—they’re cheaper, far more reliable, and largely unregulated. The United Nations treats ocean cables in much the same manner as boat traffic, meaning companies can lay and repair cables in international waters pretty much wherever they please, provided they don’t damage existing ones.So Silicon Valley will continue to pour money into technology pioneered in the telegraph era. “It’s about taking control of our destiny,” says Mark Russinovich, chief technology officer for Microsoft’s cloud services division, Azure. “We’re nowhere near being built out.”
