Demonstrators hold signs during a gathering in support of US House of Representatives Speaker Nancy Pelosi's expected visit, in Taipei, Taiwan on 2 August 2022.

China vowed Tuesday to launch "targeted military actions" in response to US House Speaker Nancy Pelosi's visit to Taiwan, as tensions flare between Washington and Beijing.

"The Chinese People's Liberation Army is on high alert and will launch a series of targeted military operations to counter this, resolutely defend national sovereignty and territorial integrity, and resolutely thwart external interference and 'Taiwan independence' separatist attempts," defence ministry spokesman Wu Qian said in a statement condemning the visit.
