In 1987 panasonic made an adventurous bet on China. At the time the electronics giant’s home country, Japan, was a global manufacturing powerhouse and the Chinese economy was no larger than Canada’s. So when the company entered a Chinese joint venture to make cathode-ray tubes for its televisions in Beijing, eyebrows were raised. Before long other titans of consumer electronics, from Japan and elsewhere, were also piling into China to take advantage of its abundant and cheap labour. Three-and-a-half decades on, China is the linchpin of the multitrillion-dollar consumer-electronics industry. Its exports of electronic goods and components amounted to $1trn in 2021, out of a global total of $3.3trn. These days, it takes a brave firm to avoid China.

Increasingly, however, under a weighty combination of commercial and political pressure, foreign companies are beginning to pluck up the courage if not to leave China entirely, then at least to look beyond it for growth. Chinese labour is no longer that cheap: between 2013 and 2022 manufacturing wages doubled, to an average of $8.27 per hour. More important, the deepening techno-decoupling between Beijing and Washington is forcing manufacturers of high-tech products, especially those involving advanced semiconductors, to reconsider their reliance on China.
