Countermeasures against US sanctions called for

The unilateral sanctions Washington has imposed on a number of Chinese entities under the pretext of so-called Russia-related factors are unjustifiable. It is natural that Beijing should respond to such "bullying and economic coercion".

That explains why China took measures on Tuesday against 12 US companies involved in the US arms sales to Taiwan and their senior executives. They include units of Lockheed Martin, Raytheon and General Dynamics. Their assets in China will be frozen and their senior executives banned from entering China.

These companies have seriously infringed on the sovereignty and territorial integrity of China. The sanctions are what they deserve.
