BEIJING (AP) — China should immediately release a Swedish book publisher who was taken off a train in front of his country's diplomats by Chinese police four days ago, Sweden's foreign minister said. The Chinese foreign ministry on Wednesday indicated Gui Minhai, the Hong Kong-based book publisher, and the Swedish diplomats who were with him may have been breaking Chinese law. Gui was first abducted in 2015, one of five Hong Kong booksellers whose disappearances became a symbol of the extent to which China was willing to reinforce its hard line on squelching political dissent and a free press despite international criticism.
