Opening a new front in its trade and technology disputes with China, the Trump administration on Monday took action to cut off a Chinese state-backed semiconductor maker from U.S. exports of components, software and technology goods.
The Commerce Department said it has put Fujian Jinhua Integrated Circuit Co Ltd on a list of entities that cannot purchase such products from U.S. firms, citing a "significant risk" that the Chinese firm's new memory chip capacity will threaten the viability of American suppliers of such chips for military systems.
It said in a statement that Fujian Jinhua "poses a significant risk of becoming involved in activities that are contrary to the national interests of the United States."
The action is similar to a Commerce Department move that nearly put Chinese telecommunications equipment company ZTE out of business earlier this year by cutting it off from U.S. suppliers.
ZTE, which had violated a deal to settle violations of sanctions on Iran and North Korea, was allowed to resume purchases of U.S. products after a revised settlement and payment of a $1 billion fine.
The action against Fujian Jinhua is likely to ignite new tensions between Beijing and Washington since the company is at the heart of the "Made in China 2025" program to develop new high-technology industries.
The world's top two economies are already waging a major tariff war over their trade disputes, with U.S. duties in place on $250 billion worth of Chinese goods and Chinese duties on $110 billion of U.S. goods.
Fujian Jinhua, which is starting up a new $5.7 billion chip factory in Fujian province, is linked to the Trump administration's accusations that China has systematically stolen and forced the transfer of American technology.
Fujian Jinhua and Taiwanese partner United Microelectronics Corp. (UMC) were accused last December by U.S. memory chip maker Micron Technology Inc of stealing Micron chip designs through poached employees, a case still under way in a California court.
UMC countersued in a Chinese court, accusing Micron of infringing its patents, leading to a temporary ban in July on sales of Micron's main products in China.
It was not immediately clear what effect the Commerce Department action will have on Fujian Jinhua's operations.
U.S. Commerce Secretary Wilbur Ross said in a statement that the Chinese firm's new plant likely was the beneficiary of "U.S.-origin technology" and its additional production would threaten the long-term viability of U.S. chipmakers.
"When a foreign company engages in activity contrary to our national security interests, we will take strong action to protect our national security," he said. "Placing Jinhua on the Entity List will limit its ability to threaten the supply chain for essential components in our military systems."
