The Economist-The battle for digital supremacy

1.1 How to engage and how not to

Designed by Apple in California. Assembled in China.' For the past decade the words embossed on the back of iPhones have served as shorthand for the technological bargain betwee the world's two biggest economies: America supplies the brains and China the brawn.

Now any more. China's world-class tech giants, Alibaba and Tencent, have market values of around 500 dollars billion, rivalling Facebook's. China has the largest online-payment market. Its equipment is being exported across the world. It has the fastest supercomputer. It is building the world's most lavish quantum-computing reserach centre. Its forthcoming satellite-navigation system will compete with America's GPS by 2020.

Amercia is rattled .An investigation is under way that is expected to conclude that Chin's theft of intellectual property has cost Amercian companies around 1 trillion dollars; stinging tariffs may follow. Earlier this year Congress introduced a bill to stop the government doing business with two Chinese telecoms firms, Huawei and ZTE. Eric Schmidt, the former chairman of Alphabet, Google's parent, has warned that China will overtake America in artificial intelligence by 2025.

This week President Donald Trump abruptly blocked a 142 dollar billion hostile takeover of Qualcomn, an American chipmaker, by Broadcom, a Singapore-domiciled rival, citing national-security fears over Chineses leadership in 5G, a new wireless technology. And so often, Mr Trump has identified a genuine challenge, but is bungling the response. China's technological rise requires a strategic answer, not a knee-jerk one. 

1.2 The motherboard of all wars

To understand what Amercia's strategy should be, first define the problem. It is entirely natural for a continet-sized, rapidly growing economy with a culture of scientific inquirey to enjoy a technologial renaissance. Already, China has one of the biggest clusters of AI scientists. It has over 800 million internet users, more than any other country, which meas more data on which to hone its new AI. The technological advances this brings will benefit countless people, Amercians among them. For the United States to seek to keep China down merely to preserve its place in the pecking order by, say, further balkanising the internet, is a recipe for a poorer, discordant-and possibly warlike-world. 

Yet its is one thing for a country to dominate televisions and toys, another the core information technologies. They are the basis for the manufacture, networking and destructive power fo advanced weapons systems. More generally, they are oftern subject to extreme network effects, in which one winner establishes an unassailable posistion in each market. This means that a country may e squeesed out of vital technologies by foreign rivals pumped up by state support. In the case of China, those rivals answer to an oppressive authoritarian  regime that increasingly holds itself up as an alternative to liberal democracy-particularly in its part of Asia. China insisits that it wants a winwin world. America has no choice but to see Chinese technology as a meas to an unwelcome end. 

The question is hwo to respond. The most important part of the answer is to remember the reasons for America's success in the 1950s and 1960s. Government programmes, intended to surpass the Soviet Union in space and weapons systems, galvanised investment in education, research and engineering across a braod range of technologies. This ultimately gave rise to Silicon Valley, where it was infused by a spirit of free inquiry, vigorous competiton and a healthy capitalise incentive to make money. IT was supercharged by an immigratino system that welcomed promising minds from every corner of the palnet. Sixty years after the Sputnik moment, Amercia needs the same combination of public investment and prvate enterprise in pursuit of a national project. 

1.3 Why use a scalpel when a hammer will do?

The other part of the answer is to update national-security safeguards for the realities of China's potential digital threats. The remit of the Committee on Foreign Investment in the US, a multi-agency bady charged with screening deals that affect national security, should be expanded so that minority investment in AI, say, can be scrutinised as well as outright acquisitions. Worries about a upplier of critical cmoponents do not have to result in outright bans. Britain found a creative way to mitigate some of its China-related security concerns, by using an evaluation centre with the power to dig right down into every detail of the hardware and software of the systmes that Huawei supplies for the telephone network.

Set against these standards, Mr Trump falls short on every count. The Braodcom decision suggests that valid suspicion of Chinese echnology is blurring in to out-and-out protectionism. Broadcom is not even Chineses; the justification for blocking the deal was that it was likely to inveset less in R&D than Qualcomm, letting China seize a leas in setting standards.

Mr Trump has reportedly already rejected on e plan ofr tariffs on China to compensate for forced techology transfer but only because the amounts were too small. Were America to impose duties on Chiense consumer electronics, for example, it would harm its own prosperitey wthout doing anything for national security. An aggressively anti-China tack has the obvious risk of a trade tit-for-tat that would leave the world's two largest economies both worse off and also more insucure. 

Mrr Trump's apporach is defined only by what he can do to stifle China, not by what he can do to improve Amercia's prospect. His record on that score is abysmal. America's federal government spending on R&D was 0.6% of GDP in 2015, a third of what it was in 1964. Yet the president's budget proposal for 2019 includes a 42.3% cut in non-defence discretionary spending by 2028, which is where funding for scientific research sits. He ahs mede it harder for skilled immigrants to get visas to enter America. He and some of his party treat scientific evidence ith contempt-specifically the science which warns of the looming threat of climate change. Amercia is right to worry about Chineses tech. But for America to turn its back on the thins that made it great is no answer.
