Funny enough, I just completed a 6-day Xinjiang road trip to the Kazakhstan border, finished yesterday...Xinjiang is unfathomably vast, humongous beautiful place, highly recommend.
There is no way China can send a large land army to aid or protect Iran from Xinjiang, that's not physically plausible or realistic.
Xinjiang is super vast and very rugged terrain. Even if Xinjiang has world-class infrastructure in the high mountains, it's still a one-lane per direction highway that can be clogged by a rogue cow on a good day, the capacity isn't there. There is no way China can sustain a land army through the Kara-Kunlun mountains into Pakistan, through Balochistan (terrorist haven), and into the Iran plateau to Tehran. It would be so logistical difficult over some of the most isolated and rugged mountain ranges on earth.
