Earlier, the Chinese Ministry of Defense said that the Chinese army is on alert amid the visit of the speaker of the US House of Representatives Nancy Pelosi to Taiwan and will conduct a series of military measures as a countermeasure.

On the evening of August 2, the Chinese Foreign Ministry also strongly protested Pelosi's visit.
