Aug 13 (Reuters) - Taiwan's foreign ministry expressed its "sincere gratitude" towards the United States for taking "concrete actions" to maintain security and peace in the Taiwan Strait and the region, it said in a statement on Saturday.

The statement came in response to comments from U.S. Indo-Pacific coordinator Kurt Campbell, who said on Friday that China "overreacted" to U.S. House of Representatives Speaker Nancy Pelosi's visit to Taiwan. (Reporting by David Kirton; Editing by Tom Hogue)
