In recent years, American warships - and temporarily also those of allied countries such as Great Britain and Canada - conduct routine cruises in the strait, inciting anger in Beijing, Telegraph reports.

China had begun military exercises near the island after Pelosi's visit in early August — where the exercises continued for weeks.
