Speaker of the US House of Representatives Nancy Pelosi made a provocative visit to China's Taiwan region recently in disregard of the Chinese side's stern warnings. The visit seriously infringes on China's sovereignty and security, seriously undermines China's territorial integrity, seriously jeopardizes peace and stability across the Taiwan Straits, and seriously erodes the political foundation of China-US relations. The Chinese side has been compelled to take countermeasures. The US side has been pushing disinformation to confuse right and wrong and confound black and white, criticizing China's legitimate countermeasures and trying to mislead the world about the Taiwan question. It is necessary to set the record straight with facts and lay bare the US's hegemonic nature and gangster logic.
