All of the trade routes are for bilateral trade..Are you sure China,who has so much trouble to make business with these countries because of inadequate period and means(Most of Chinese Trucks have to wait significant amount of time) to make trade with these countries(as Most of these pass remains open for 5-6 months),they're going to allow Pakistan to make trade using these,which are overburdened??Also,what about treaties which is going to make Bilateral trade routes multilateral??Do you even know that most of these trade routes doesn't allow foreigners??and what about transport cost??Using Chinese routes means hundreds of KMs of extra travelling cost,not to mention the extra fee that China might charge as "Transit fee".
now...
Torugart Pass-Still not open for a third country.
Irkeshtam pass is only way into Kyrgyzstan via China,but it is overburdened.It is quite unlike that China will allow a Pass to a third country when they're having difficulties right now..I'm not taking proposed routes into account.
The video of Irkeshtam pass in my previous speaks for itself, also read the wiki description that I included in my post, it is open for whole year, except for Kyrgyz and Chinese holidays. Torugart pass is still work in progress, and both will have railway in the near future, as part of Chinese Belt and Road (Silk) initiative.
This is a 5 year old video of Torugart pass, I am sure it is much different today:
As for high mountain passes being closed in cold winter months, this is mainly because of bad weather and snow combined with still undeveloped roads and railways. Once roads and railways are fully developed and there is crew to cleanup snow from the roads and tracks, the closed months will no longer be closed.
Transport cost by truck and rail is not cheap and in Central Asia, there is no cheap short cut sea route, because it is a land locked region.
Here is some info on cost and time needed for shipment to the region:

About China not allowing foreigners to trans-ship through their territory, just talk to anyone in the logistics and shipping industry, they will give you the real picture. To reach Central Asia from Bangladesh, a container costs around $6000 via Bandar Abbas, but around $10k via Chinese ports and then by train to Amaty or Bishkek. The Chinese route is definitely long, because they are traveling by train from Hong Kong, Shanghai or other northern ports, that is why it costs more, but its faster and more reliable. The Iran route is not as reliable. Pakistan route will not only be good for Pakistan, it will open up a great route for Bangladeshi businessmen as well, as Bangladesh is one of the biggest importer of Uzbek cotton.
So people are doing it (third country going through China to Central Asia) now and has been doing it for some years. The new routes will make things cheaper and quicker. The main container rail route from China to Central Asia now is via Alataw/Alatau pass Kazakhstan, which will soon be supplemented by Khorgos as I mentioned in my previous post.
Alashankou Railway Station - Wikipedia, the free encyclopedia
"Alashankou railway station (
Chinese: 阿拉山口站;
pinyin:
Ālāshānkǒu zhàn), also known as
Alataw Pass railway station (also spelt
Alatau and
Ala Tau) is a
railway station in
Börtala Mongol Autonomous Prefecture of China's
Xinjiang Uyghur Autonomous Region.
Located on the Chinese side of the
Dzungarian Gate pass through the
Dzungarian Alatau mountain range at the 2358.376 km point of
Lanxin railway, it is the last station on the
Northern Xinjiang branch of the
Lanxin railway before entering Kazakhstan. For the first twenty-plus years of its history it was the only railway
port of entry in western China; during this time, the volume of international rail freight going through the Alashankou port of entry grew from 160,000 tons in 1991 to 15,160,000 tons in 2011.
[1]
In another report (not quite consistent with the previous one), the volume of rail freight crossing the border at Alashankou during the first 10 months of 2011 were reported as 8,921,000, which was said to be a 12.8 increase over the previous year. The volume of traffic, measured by weight, going from Kazakhstan to China is much higher than from China to Kazakhstan (7,412,000 tons vs. 1,509,000 tons). The main commodities that went from Kazakhstan to China via Alashankou were
iron ore, high-carbon
ferrochrome,
wheat, and
steel. Among the goods shipped from China to Kazakhstan, the main groups were steel (in particular, steel pipes), electronics, and
tomato paste.
[2]
There is also a passenger train,
Almaty-
Urumqi, that crosses the border at Alashankou.
It is expected that the second railway port of entry on the Sino-Kazakh border, at
Khorgos, will open in the late 2012.
