Not one of the signatories was a Muslim majority nation.
China then orchestrated a letter from 37 nations supporting its repressive policies. That letter commended China's efforts in "protecting human and promoting human rights through development," echoing Chinese propaganda points about its detention and re-education camps.
That letter was signed by 14 Muslim majority states, all members of the Organization of Islamic Cooperation: Algeria, Bahrain, Egypt, Kuwait, Saudi Arabia, Oman, Pakistan, Qatar, Somalia, Sudan, Syria, Tajikistan, Turkmenistan, and the United Arab Emirates.
Last December, the human rights committee of the OIC mentioned "disturbing reports" of China's actions against Muslims in a series of tweets.
That all seemed to change by March, when the OIC issued a report saying that it "commends the efforts of the People's Republic of China in providing care to its Muslim citizens; and looks forward to further cooperation between the OIC and the People's Republic of China."
This was the precursor to last week's sham of a letter supporting China fully in its oppression of Muslims.
Muslim nations love to talk about pride and honor. When they attack Israel in the UN they claim that they are merely defending their fellow Muslims from attacks by others.
This willingness to suck up to China shows that they not only have no pride and no honor, but that they really don't even care about their fellow Muslims.
