The Chinese government imposed sanctions on seven companies on Friday in response to recent announcements by the United States that it would sell military equipment to Taiwan and provide other assistance in this sector.
Taiwan is a self-governing island that China claims is part of its territory.
The sanctions also come in response to the recent approval of the annual defense spending budget by the US government, which, as the Chinese Foreign Ministry said in a statement, "includes numerous negative positions on China."
China opposes US aid to Taiwan and often imposes sanctions on companies associated with them, usually after products to be sold or aid packages are announced.
Sanctions generally have limited impact because American defense companies do not sell weapons or other military equipment to China. The United States is Taiwan's main arms supplier.
The seven sanctioned companies are: Insitu Inc., Hudson Technologies Co., Saronic Technologies, Inc., Raytheon Canada, Raytheon Australia, Aerkomm Inc. and Oceaneering International Inc., the Foreign Ministry statement said.
Any assets they have in China will be frozen, while Chinese organizations and citizens are prohibited from engaging in any activities with these companies, the statement said.
US President Joe Biden last week authorized up to $571 million for Department of Defense materials and services as well as military training for Taiwan.
The Department of Defense also announced the approval of a $295 million package of weapons to be sold to Taiwan.
The US defense bill increases military spending to $895 billion and directs resources toward a more confrontational approach toward China.
It creates a fund that could be used to send military resources to Taiwan, similar to how the US has supported Ukraine. The bill also extends a ban on US military purchases of Chinese products, such as drone technology.
Zhang Xiaogang, a spokesman for the Chinese Ministry of Defense, said earlier this week that the US is promoting the "so-called threat from China" to justify increased military spending.
"US military spending is at the top of the world and continues to increase every year. This exposes the warlike nature of the US and its obsession with hegemony and expansion," he said.
The Foreign Ministry said that the US's recent moves violate agreements between the two countries on Taiwan, interfere in China's internal affairs, and undermine the country's sovereignty and territorial integrity.
Taiwan's government said earlier this month that China had sent dozens of ships to nearby waters to conduct exercises to blockade the island, a move that Taiwan said undermines peace and stability and harms international shipping and trade. China has not confirmed or commented on the claims./VOA
