First, there is geopolitics and national security. Digital technologies allow foreign powers to hack industrial networks, conduct cyber-espionage, and manipulate social media. Russia has been accused of interfering in elections in the US and other Western countries through fake news sites and the manipulation of social media. The US government has cracked down on the Chinese giant Huawei on fears that its links to the Chinese government make its telecoms equipment a security threat.

Second, there are concerns about individual privacy. Internet platforms are able to collect huge amounts of data on what people do online and off, and some countries have stricter rules than others to regulate what they can do with it. The EU, for example, has enacted fines for companies that fail to protect the EU residents’ data.

Third, there is economics. New technologies give a competitive edge to large companies that can accumulate enormous global market power. Economies of scale and scope and network effects produce winner-take-all outcomes, while mercantilist policies and other government practices can result in some firms having what looks like an unfair advantage. For example, state surveillance has allowed Chinese firms to accumulate huge amounts of data, which in turn has enabled them to corner the global facial recognition market.

A common response to these challenges is to call for greater international coordination and global rules. Transnational regulatory cooperation and anti-trust policies could produce new standards and enforcement mechanisms. Even where a truly global approach is not possible—because authoritarian and democratic countries have deep disagreements about privacy, for example—it is still possible for democracies to cooperate among themselves and develop joint rules.

The benefits of common rules are clear. In their absence, practices such as data localization, local cloud requirements, and discrimination in favour of national champions create economic inefficiencies insofar as they segment national markets. They reduce the gains from trade and prevent companies from reaping the benefits of scale. And governments face the constant threat that their regulations will be undermined by companies operating from jurisdictions with laxer rules.

But in a world where countries have different preferences, global rules—even if feasible—are inefficient in a broader sense. Any global order must balance the gains from trade (maximized when regulations are harmonized) against the gains from regulatory diversity (maximized when each national government is entirely free to do what it wants). If hyper-globalization has already proved brittle, it is in part because policymakers prioritized the gains from trade over the benefits of regulatory diversity. This mistake should not be repeated with new technologies.

In fact, the principles that should guide our thinking on new technologies are no different from those for traditional domains. Countries may devise their own regulatory standards and define their own national security requirements. They may do what is required to defend these standards and their national security, including through trade and investment restrictions. But they have no right to internationalize their standards and try to impose their regulations on others.

Consider how these principles would apply to Huawei. The US government has prevented it from acquiring American companies, restricted its operations in the US, launched legal proceedings against its senior management, pressured foreign governments not to work with it, and, most recently, banned US companies from selling chips to Huawei’s supply chain anywhere in the world.

There is little evidence that Huawei has engaged in spying on behalf of the Chinese government. But that does not mean that it will not do so in the future. Western technical experts who have examined Huawei’s code have been unable to rule out the possibility. The opacity of corporate practices in China could well obscure Huawei’s links to the Chinese government. Under these circumstances, there is a plausible national security argument for the US—or any other country—to restrict Huawei’s operations within its own borders. Other countries are not in a position to second-guess this decision.

The export ban on US companies, however, is harder to justify on national security grounds than the ban on Huawei’s US-based operations. If Huawei’s operations in third countries pose a security risk to those countries, their governments are in the best position to assess the risks and decide whether a shutdown is appropriate.

Moreover, the US ban confronts other countries with severe economic repercussions. It creates significant adverse effects for national telecoms companies like BT, Deutsche Telekom, Swisscom, and others in no fewer than 170 countries that rely on Huawei’s kits and hardware. Perhaps worst hit are poor countries in Africa that are highly dependent on the company’s cheaper equipment.

In short, the US is free to close its market to Huawei. But US efforts to internationalize its domestic crackdown lack legitimacy. The Huawei case is a harbinger of a world in which national security, privacy, and economics will interact in complicated ways. Global governance and multilateralism will often fail, for both good and bad reasons. The best we can expect is a regulatory patchwork, based on clear ground rules that help empower countries to pursue their core national interests without exporting their problems to others. Either we design this patchwork ourselves, or we will end up, willy-nilly, with a messy, less efficient and more dangerous version. © 2020 Project Syndicate
