This is all talk like how the KMT spend up until the 80s loudly proclaiming how they will "liberate" China from the commies. These Uyghur takfiris are too busy stealing land from Syrians and setting themselves up as settlers on Syrian land to seriously care about entering China. You might have some true believers try before getting liquidated in Afghanistan by the Taliban, but the leadership knows they have a much sweeter deal pillaging Syria.
