To get from Kyrgyzstan to Pakistan, one needs to drive through an 575 km section inside China, the one from "Irkeshtam Port, 309 Provincial Road, Ulugqat, Kizilsu, Xinjiang, China" to "Kunjirap Daban, Tashkurgan, Kashgar, Xinjiang, China", part of which is the Chinese section of the Karakoram Highway.
This question is about getting my own vehicle through, on a journey from Georgia to India (to avoid dangerous parts of Pakistan).
How would I go about getting my vehicle through this section, whom to contact? As this is not a very long section, so paying for a Chinese guide is OK. Obviously affixing temporary Chinese licence plates is fine if required.
There are several questions about driving foreign vehicles in China, but this section is about this special section specifically, as the rules and practices about foreign vehicles in China can be different in each province.
Is it possible to cross this section in January? Wikipedia quotes that the Khunjerab Pass China-Pakistan border crossing is only open May to December, but maybe there is some way to do it in January? This will be a Volvo Laplander 4x4 (or even 6x6) offroad vehicle, so should have no technical problems.
If that route is not possible in January, then what it would take (from the legal issues) to drive this route: depart from Kyrgyzstan, from "Irkeshtam Port, 309 Provincial Road, Ulugqat, Kizilsu, Xinjiang, China", via "Phoenix Tea House, 219 National Road, Gar, Tibet, China" to "Zhangmuzhen, Nyalam, Xigaze, Tibet, China" and entering Nepal there (omitting Pakistan completely), to continue to India?
Place names in quotes in this question are what Google Maps recognizes and allows to plot a route between.
