Driving from UK to thailand

[Banebdjed]

Hi, i am going to see some family in Thailand and was intending to fly. However, this crazy idea came to my head how it would be once in a life-time experience to actually drive it. My crazy notion has turned into something i think i am actually going to do.
When i first started planning this journey i began by planning to go through europe into Turkey then though Iran, Pakistan, India, Bangladesh then Burma.
However after doing some more research a realized that in the current climate this route was possibly not advisable.
Back to the drawing board i decided to head through europe through Ukraine and into Russia, then into Kazakhstan Via Saratov and along the Kazakhstan M32 all the way to China where i would continue on to Laos then finally Thailand.
However, i was close to admitting defeat and scrapping the idea after learning how bad the roads in Russia and Kazakhstan can get and at some points i have learnt they are reduced to mere dirt track and rubble. This is not ideal when having thousands of miles of ground to cover.
However, i did not give up and continued researching, and while researching i stumbled upon someones you-tube channel that was dedicated to motorways in Russia. What i saw was like a god send. It was it was beautiful paved carraigeway. With a knew lease of life i got back to the drawing board and modefied my route to come through Europe and into Russia via Lithuiania and Latvia. It is a bit further north than i would like and Further south through the Ukraine is the geographical natural route. But if it means me being able to travel relatively risk free of puncture or break-down and mentain a speed of between 60mph and 80mph then it is well worth it and i am sure will end up quicker in the long run.
So, i now plane to hit the Russian M9 from Latvia into Moscow, and from Moscow i will take either the M5 or the M7 to meet the M51 in the South, then i will drive along the M51 into Omsk where i will turn down the M38 and cross the Russian border into Kazakhstan then carry on down the M38 to the Chinese border crossing.
Only thing is, i cannot find anything on the internet about the Kazakhstan M38 and can only see the trail on google-maps. I can find bits of informaation regarding the Kazakhstan M32 and M36, but nothing regarding the M38.
It seems to me that the M38 is the best option. Even if it is not the best quality road in Kazakhstan, geographically it is a far lesser journey from Omsk to the Chinese border than the other two routes, so would probably be worth it. However, somethings i would like to know is regarding the state of the M38. Is it a good road? Also, is there a border crossing South of Orms that i could cross into Kazakhstan? and where is the Chinese border crossing? would i be able to get to it along the M38? Other things i need to know is, how do i obtain a Chinese driving license and get round the fact they do not recognise the International driving license? and also how do i go about obtaining a permit to get my vehicle into China?

Would be greatful if anyone could help me on this
