Beginning in 2014, the Chinese government, under the administration of Chinese Communist Party (CCP) General Secretary Xi Jinping, incarcerated more than an estimated one million Turkic Muslims without any legal process in internment camps. Operations from 2016 to 2021 were led by Xinjiang CCP Secretary Chen Quanguo.[2] It is the largest-scale detention of ethnic and religious minorities since World War II.

So, yes, the genocide in Gaza is criminal, no less egregious or evil and those committing or supporting it should be brought before a tribunal, but they're still rookie numbers compared to the CCP. Even if you go all the way back to the Nakba. There's simply no way around it.
