Note: Taiwan is claimed by the People's Republic of China but administered by the Republic of China (see Political status of Taiwan). Hong Kong and Macau are claimed as provincial-level divisions, but as listed on the constitutional documents and joint declarations their statuses are better to be interpreted as first-level divisions instead.[source?]
