Beijing has decided to sanction Nancy Pelosi and her immediate family over her trip to Taiwan this week, a Chinese Foreign Ministry spokesperson announced on Friday.

The US House speaker’s trip to Taiwan was an “egregious provocation” and because of this, “China decides to adopt sanctions on Pelosi and her immediate family members in accordance with relevant laws” of the country, the spokesperson said in a statement.

Pelosi traveled to the self-governed island “in disregard of China’s grave concerns and firm opposition,” the statement read.

Her visit “gravely undermines China’s sovereignty and territorial integrity, seriously tramples on the one-China principle, and severely threatens peace and stability across the Taiwan Strait,” it added.
