As new United States export restrictions threatened to thwart Beijing's goals for technological self-sufficiency, shares of major Chinese chipmakers saw a loss of $8.6 billion in market value on Monday. 

On Monday, reports said Hua Hong Semiconductor lost 9.4%, Shanghai Fudan Microelectronics fell 20.2%, and Semiconductor Manufacturing International Corp, China's largest chipmaker, fell 4% in Hong Kong. 

The steep losses followed Washington's announcement of new export curbs on Friday, which limit the sale of chips produced with US technology unless suppliers receive an export license. 

According to reports, the regulations further prevent the transfer of manufacturing equipment that would enable China to create its own machinery and prohibit US people or businesses from cooperating with Chinese chipmakers without explicit authorization. 

On Friday, the US Commerce Department announced the addition of 31 companies to its "unverified list" to make it more difficult for Chinese companies to manufacture or buy advanced computer chips critical to innovative technologies. 

“Most of the new companies are not listed, but the restrictions are still affecting overall sentiment in the market,” head of research at Kingston Securities in Hong Kong Dickie Wong said. 

According to end users, the Chinese semiconductor sector accounts for a quarter of global demand. 

“The tensions between China and the US are not going to ease up, so any addition to any entity list is not going away. We have to expect that in the near term, more companies will be added to the list as well,” Wong added.
