Summary
China has imposed an export ban on dual-use products to 28 U.S. defense contractors, including Lockheed Martin, Raytheon, Boeing, and General Dynamics, in retaliation for U.S. arms sales to Taiwan.
Ten firms were barred from trade and investments in China.
Beijing condemned the arms sales, citing violations of the One China principle and threats to Taiwan Strait stability.
The ban follows Taiwan’s recent receipt of advanced U.S. military equipment, including Abrams tanks, as the island bolsters its defenses against China’s military activities.
I think you misunderstand the complexity of the situation. The US would go to war on behalf of our economic interest and allies depending on the leadership, but not likely initiate itat the moment. China is under immense pressure of a different type and may use military might in the future to change it’s power, but both have challenge which make your statement too black and white to be valid. It’s more gray.
The following are all Foreign Affair, but give good long form context to current challenges.
