Thousands of miles of fiber optic cable lying at the bottom of the world’s oceans carry more than 95% of the world’s data, from phone calls and emails to encrypted military secrets.

Now, those submarine cable systems are at the forefront of a new rivalry between China and the U.S. over who controls the flow of big data.

“Undersea cables … have now become a weapon of war in this new Cold War between China and the U.S.,” Reuters reporter Joe Brock says.

Today, On Point: The new battle over undersea cables.

Transcript

MEGHNA CHAKRABARTI: The Internet’s true circulatory system lies deep underwater, nearly 900,000 miles of fiber optic cables snake across ocean floors, transporting the world’s information, financial transactions, military and diplomatic traffic. American firms have dominated the cable laying business since the start.

But now China is entering the scene with one of the world’s most advanced and far-reaching subsea cable networks. It’s a $500 million undersea fiber optic cable that would link Asia, the Middle East and Europe, and it snapped the United States to attention. Here’s Republican Congressman Brian Mast of Florida in March, speaking about the bipartisan undersea cable Control Act which passed the House.

BRIAN MAST: Chinese companies heavily subsidize, of course, by the PRC. The communist government have started investing heavily in owning and supplying subsea cables. Think things like voice communications, data, internet, trillions of daily international financial transactions, things that you don’t want China getting a hold of.

They weaponize every bit of social media that they can. They try to make these capabilities fit their own nefarious ends. So do we really think for a second that they would not do the same with undersea cables? I’m not going to be fooled into thinking that.

CHAKRABARTI: The Chinese cable counted telecom giant Huawei Technologies as one of its shareholders. Robert Spalding of the Hudson Institute told Bloomberg News that’s a cause for concern.

ROBERT SPALDING: In Canada, for example, we’ve seen data be rerouted to China. We’ve also seen, for instance, what happened with the African Union. So it’s clear that Huawei has a pattern of behavior that shows data being moved to China.

CHAKRABARTI: However, you won’t hear such bellicose talk from Europe because France and Germany have already said they will not isolate China or diplomatically disparage Beijing. Despite the risks feared by the United States. This is Emily Taylor of Oxford Information Labs.

EMILY TAYLOR: You don’t take unnecessary risks. But there are many risks associated with taking a nationalistic view to technology. It can potentially break the architecture of the Internet.

CHAKRABARTI: The U.S. and China are already deep into a power struggle that will define the future. It’s a race for silicon chips, rare earth minerals, 5G technology, artificial intelligence, space exploration, navies and air forces, consumer products and cultural influence. Now, as some have put it, there’s a war under the waves.

So how should we best understand the rising tensions over China’s new undersea fiber optic cables, not just from the U.S. perspective, but … the world? Well, Nicole Starosielski joins us. She is a professor of media culture and communication at New York University and an expert in undersea fiber optic cables. She’s author of the book The Undersea Network. Nicole, welcome to On Point.

NICOLE STAROSIELSKI: It’s great to be here.

CHAKRABARTI: Also with us is Joseph Keller. He’s a visiting fellow at the Brookings Institution’s Center for Security Strategy and Technology. Joe, welcome to you.

JOSEPH KELLER: Thanks so much for having me.

STAROSIELSKI: So first, let me have you both describe really the extent and importance of these undersea fiber optic cables. I mean, Nicole, I understand that they carry, what, 95 to 99% of the world Internet traffic.

STAROSIELSKI: Yes. When the Internet goes between continents at large, the 99% of the time, over 99% of the time goes on the very bottom of the seafloor on undersea cables. They’re integral to global communications. We don’t have the Internet as we know it today without them.

CHAKRABARTI: Okay. And, Joe, as I said earlier, the United States and U.S. companies have basically had the lead on laying cable for a long time now. But describe a little bit more about how the networks work. Does it mean that those companies essentially control what traffic goes through those cables?

KELLER: Yes. So stakeholders come together to try to make investments in some of these telecom projects. They involve ten, 12 individuals. It requires participation, cooperation between countries, between governments and between companies, even though they do not share the same regions.

CHAKRABARTI: So, Nicole, I guess what I’m trying to understand before we get deep into what China is doing, is, you know, trying to put the concerns that we heard in the intro say, for example, Congressman Brian Mast, into context for right now. With all those basically U.S. owned cables, are those U.S. tech companies then deciding what traffic goes? Where could they do the same things that the United States is accusing China of potentially doing with its fiber optic undersea cable?

STAROSIELSKI: I think the threat is a little overstated. Well, certainly anyone who owns a subsidy cable system could halt all the traffic on that cable system, monitor all the traffic on that cable system. That’s not what they choose to do, because that wouldn’t be economically viable. That wouldn’t be politically viable. There are a lot of reasons that the system remains open as it is today.

CHAKRABARTI: Okay. So does that mean that it would remain open and you believe it would remain open with China’s cable connecting what, Asia, the Middle East and Europe?

STAROSIELSKI: I believe that that would be an open system that has traffic transiting it in the same way that many other cables around the world do.

CHAKRABARTI: Okay. So we’ll talk more about that in a few minutes because, I mean, clearly, we’re doing this hour because not everyone was as confident. … I want to hear from both of you about China’s new fiber optic cable. It’s called SeaMeWe-6. What should we understand about it?

KELLER: So this has been a very provocative issue. So earlier this year, around February, construction for a cable from France to Singapore, I think is emblematic of these rising U.S.-China tensions, because mainly reports suggest that the U.S. has been sabotaging telecom deals like this with China for years.

CHAKRABARTI: Tell me more.

KELLER: So reports suggest that this is one of at least six private undersea cable projects that have come together over the Asia-Pacific region. … It links a lot of territories, including landing stations on the continent of Africa. The thing here, though, is that several years ago when the project came together, the consortium of stakeholders agreed that the entity laying the cable, the fiber optic cable, would be a Chinese associated company.

But given the threat that U.S. proceed from associated Chinese companies laying the cable and foreign adversaries, they decided to undertake what has been seen as an influence campaign behind the scenes, providing favors, for example, through grants, training grants and money for individuals involved in participating the stakeholders to get them to flip their decision.

So individuals had decided that verbally we would go with a Chinese cable later, this case called HMN Tech. After this influence campaign, individuals for many reasons decided they would go with a U.S. backed cable, their entity called Subcom. So that’s where we are today. A story that started several years ago with a larger influence of Chinese backers and stakeholders now has a greater influence in the U.S. and in the intervening time.

Stakeholders from China have left that project and have struck out on their own to try to construct what has been seemingly seen as competing and reactionary cables at the same time along similar routes.

CHAKRABARTI: Okay, Nicole, do you want to add to that? Because this seems to be, you know, kind of both a diplomatically complex and even technologically complex story that’s unfolding.

STAROSIELSKI: Yeah, I would just say that the … initial subsea cable system had members of many countries involved, not just China. And that these systems are typically, have typically been, what are called consortium systems. So there are consortia that have, you know, the United States, U.S. based companies, France based companies, China based companies all collaborating together to lay this global kind of international projects.

And so I think that it’s important to keep that context in mind, that there’s been a lot of collaboration in the industry and that this hasn’t typically been something that governments have stepped in to moderate that international collaboration in the way that they’re strongly doing now.

CHAKRABARTI: Governments being, I mean, specifically the United States stepping in?

STAROSIELSKI: Specifically, the United States. There’s always been a role for government, but this kind of action we’ve not seen before.

CHAKRABARTI: Okay. Joseph Keller, do you want to add to that?

KELLER: No, I think Nicole hit it right on the head. What is essential here is the collaboration between countries, between governments, because of the landing points of these cables. Permission is required for projects to go forward. And generally, all stakeholders stand to benefit from productive and successful execution of these projects. But given the specific stance that the U.S. has against China. It is creating tensions and difficulties for all projects that involve China, even for those who are not directly affiliated with it.

CHAKRABARTI: Okay. Now, Nicole, I think Joe had mentioned this a minute ago, that the U.S. has actually forced changes in fiber optic cable routing on several other projects in the Asia Pacific region over the last several years. Did I hear that correctly?

KELLER: That’s right.

CHAKRABARTI: Does that mean, Nicole, that there are miles and miles of undersea fiber optic lying around, not being used right now?

STAROSIELSKI: Well, they were not constructed in the way that they had initially been planned, either to China, Chinese territory or by Chinese suppliers.

CHAKRABARTI: Okay. So because the United States successfully just stopped the completion of those particular cables … is SeaMeWe-6, the project that’s really gotten all this public attention … still going forward?

KELLER: It is still going forward. You mentioned this at the top. It’s expected to be finished around 2025. And so this is a project that has been successful going forward, just without those Chinese stakeholders.

MEGHNA CHAKRABARTI: Steve Arsenault is director of Global Subsea Solutions for IT Telecom, a Canadian fiber optic cable laying firm. And he says people don’t realize that much of what they do on the Internet travels on the ocean floor.

STEVE ARSENAULT: There is no doubt that a misconception exists that global communications are somehow facilitated by satellites. I mean, it’s funny to me because, you know, you ask anyone, you know, what, this signal path takes for a given trans-oceanic phone call, and almost no one will tell you that it’s through an underwater cable. But the fact remains, there are literally thousands and thousands of kilometers of cable underwater just lying there.

CHAKRABARTI: Rick Chislett also works for IT Telecom, he spent 41 years on its cable laying ships as the manager of splicing and testing. He’s semi-retired in Windsor, Nova Scotia, now, but he’ll be back out on the ocean off the coast of Denmark in a couple of days. So we asked him, what’s it like laying fiber optic cable around the world?

RICK CHISLETT: My responsibility was managing the splicing and testing on board. I also look after the loading of the vessels just to make sure that the cable is stored in a hole and in the correct manner. Today, I checked the crew manifest and onboard our ship right now there are 50 crew members. And they are in transit to load cable. And then it will proceed to Denmark. And in Denmark, there is more cable to be loaded. They will be testing and jointing.

On some projects when we lay close to shore where cable can become damaged by fishing anchors, we will need to bury it. And we use what we call a subsea plow. And we tow this behind the vessel. Plow weighs roughly about 30 ton. The cable will leave the ship, go down to the seabed, go through the plow and out the back end of the plow. I will create a trench depending on the seabed conditions, soft or how hard it is, it could be carried to a maximum of two meters.

We were on a particular project about three years ago, off the west coast of South America and the bottom conditions off the coast is very mountainous. And we were toeing the sea plow behind us. We came to an area where it was a downslope and normally on downslopes, our survey team are able to identify them, and the C-Plow operators are able to slow it down.

But for some reason it didn’t slow it down fast enough. It overran the cable, and it damaged the cable at that time. The plow overturned on its side, so the ship came to a complete stop. The cable damage was repaired in probably I think about 20 hours, and the plow damage took about two days.

We do get a lot of people who spend a lot of years out on the water and enjoy it. The ship crew becomes something like a family, you know. Everybody gets along and that kind of thing. And you have to because you’re on a vessel that’s only 115 meters long. Food is good. Which is always great. For me, I worked for 40 plus years at this business. And I feel that I helped to connect families together, people together from country to country. I feel good about contributing that to the world. And I have to say, I’ve worked all over the world.
