The Chinese commerce ministry said on Thursday that it had added 10 US companies to its so-called "Unreliable Entity List" for their involvement in arms sales to Taiwan, which China regards as part of its territory, Reuters reported
Effective from Thursday, the blacklisted companies, which include various units of Lockheed and General Dynamics, will be banned from exporting to and importing from China or making new investments in the country, according to the commerce ministry.
According to AFP, they will be prohibited from import and export activities or making new investments in China, while their senior managers will be banned from entering the country, the ministry said.
Last Friday China announced sanctions on seven US military-industrial companies, including Boeing subsidiary Insitu, also over US military assistance to Taiwan.
The self-ruled island is a key point of contention between Beijing and Washington.
China claims Taiwan as part of its territory and has said it will not renounce the use of force to bring it under its control.
Washington does not recognize the democratic island diplomatically but is its strategic ally and largest supplier of weapons.
