Amnesty International has decried the "woefully inadequate" international response after the U.N. released a bombshell report last year detailing a litany of abuses in China's Xinjiang region.

On Thursday, the first anniversary of the report, Amnesty lamented that the international community, including parts of the United Nations, had "shied away from the kind of resolute steps needed to advance justice, truth and reparation for victims."

The rights group singled out U.N. rights chief Volker Turk for failing to "clearly emphasize the urgent need for accountability for (China's) alarming violations."
