Chinese Foreign Ministry announced Friday to sanction US House Speaker Nancy Pelosi and her immediate family members because she disregarded China's serious concern and firm opposition and insisted on visiting China's Taiwan region.  

It seriously interferes in China's internal affairs, undermines China's sovereignty and territorial integrity, tramples on the one-China principle and threatens peace and stability in Taiwan Straits, Foreign Ministry Spokesperson said.
