The U.S.-China tech fight spreads

More companies around the world are realizing that they have little choice but to turn their backs on Huawei, as the tech rift between the U.S. and China widens.

Huawei’s blacklisting doesn’t just affect U.S. companies. “Under Washington’s export control guidelines, third-country suppliers to blacklisted entities need to apply for licenses if U.S. content exceeds 25 percent of the value of their products or services,” the FT explains. That has left companies scrambling to work out if they need to limit their sales to the Chinese company.

• The British semiconductor designer ARM said it would stop licensing technology to Huawei’s chip unit, because some of its designs contain technology from the U.S. And the FT reported that Panasonic had halted shipments of some components to Huawei for similar reasons. The company later denied the FT report.

• Mobile carriers in Britain have stopped offering Huawei phones to some customers, Amie Tsang of the NYT reports. Cellphone companies in Japan are considering similar moves. They’re concerned about Google pulling support for the phones; it has said it will no longer offer Huawei the full version of its Android operating system.
