(Reuters) - U.S. Secretary of State Mike Pompeo on Thursday urged Indonesians to focus on the treatment of Muslim Uighurs in China, describing it as the “gravest threat” to religious freedom in a speech to an Islamic group.On a trip to the world’s largest Muslim majority country, Pompeo praised Indonesia’s tradition of tolerance, but urged Jakarta to resist China’s entreaties to “look away from the torments of your fellow Muslims”. Pompeo said China had brutalised its Uighur minority in Xinjiang province, corralling them in huge detention centres and forcing some to eat pork during the Islamic holy month.In his address to the youth wing of Indonesia’s largest Muslim group, he also accused China of separating Uighur children from their parents and imposing sterilisations. China denies mistreating Uighurs and says the camps are vocational training centres that are needed to tackle extremism and promote development. Indonesians are typically vocal about the mistreatment of Muslims, but the backlash against abuses of Uighurs has been comparatively muted.
