Detained Bookseller Says Sweden Is Using Him as a ‘Chess Piece’

BEIJING—A Swedish bookseller detained by Chinese authorities surfaced Friday in a police-arranged appearance in which he accused Stockholm of using him for political gains.

The case of Gui Minhai, who was seized off a Chinese train while traveling in the company of Swedish diplomats last month, has triggered broad condemnation, with Sweden’s foreign minister decrying the act earlier this week as a “brutal intervention” and protesting a lack of consular access to its citizen.
