HONG KONG-CHINA-RIGHTS-POLITICS-DIPLOMACY

A nun holds a candle as she attends a vigil for terminally-ill Nobel laureate Liu Xiaobo in Hong Kong on June 29, 2017. Liu wants Chinese authorities to let him get treatment abroad, friends say, as officials said his cancer has spread throughout his body. The Nobel Peace Prize winner, who was sentenced to 11 years in prison in 2009 for "subversion" after calling for democratic reforms, was released on medical parole after being diagnosed with terminal liver cancer last month, his lawyer said this week. / AFP PHOTO / Anthony WALLACE (Photo credit should read ANTHONY WALLACE/AFP via Getty Images)
