The US has reneged on its commitments, openly played with fire and pitted itself against the 1.4 billion Chinese people, and none of this will end well.
Pelosi has landed in Taiwan, opening an era of high-intensity competition between China and US over Taiwan Strait. Taiwan is close to Chinese mainland and Beijing has sufficient cards at hand. We will play them one by one confidently. The PLA is announcing a series of actions.
The US & Taiwan have made provocations together first, whereas China has been compelled to act in self-defense. Any countermeasure to be taken by China would be a justified & necessary response to the US oblivion to China's repeated démarches and the US’s unscrupulous behavior.
