U.S. restriction on chipmakers deals critical blow to Huawei

HONG KONG (AP) — The latest U.S. sanctions on Huawei threaten to devastate China’s first global tech competitor, escalating a feud with Beijing that could disrupt technology industries worldwide.

Huawei Technologies Ltd. is one of the world’s biggest producers of smartphones and network equipment, but that business is in jeopardy after Washington announced restrictions on use of American technology by foreign companies that produce its processor chips.

The conflict is politically fraught because Huawei is more than just China’s most successful private company. It is a national champion among industries the ruling Communist Party is pushing to develop in hopes of transforming China into a global competitor in profitable technologies.

Huawei has few alternatives if Washington refuses to allow its suppliers of processor chips to use American technology. The company has developed some of its own chips but the chipmakers that it contracts to manufacture them use American equipment. Even non-U.S. producers such as Taiwanese chipmaking giant TSMC need American components or manufacturing processes.

“Every electronics system that Huawei produces could be negatively impacted,” said Jim Handy, semiconductor analyst for Objective Analysis, in an email. “Most China-based alternatives haven’t yet been established.

Huawei has few options to turn to for high-end chipsets as China’s largest semiconductor manufacturer, SMIC, is currently only able to produce chips that are two generations behind TSMC’s.

“Huawei had already begun to shift some production from TSMC to SMIC, although SMIC cannot yet produce Huawei’s latest Kirin 980 chipset,” said Neil Thomas, a research associate at U.S. think tank Paulson Institute. “But SMIC can probably manufacture...
