Can someone more techy explain?
In my understanding based on the limiting information available this will be done at peering level of the ISP. IP assignment will still be handled the same and the user will not notice anything, besides a possible (large) performance penalty. This will be handled in the backbone and ISPs won't be allowed to have international uplinks any more and will peer directly with the NIG which in turn provides the international uplink.
I am not sure how this will affect providers who physically own their own international uplinks, like Telcotech and NTT. I am guessing that the NIG is a metaphor in this instance. Unless they cut the cable and shove it in a government facility, it will mean giving the government direct access, which they already have, because those ISPs follow government orders or lose their licensing. How many years did they spend on those submarine cables? They won't be cut, but they will be monitored.
Now speaking about monitoring. You have to understand the extreme amounts of data involved. In order to monitor the data you need to pass it to a CPU. Cisco core routers purposefully don't pass network traffic to the CPU because high traffic overloads the processor. When network traffic is analyzed, selected
parts of it are passed to the CPU temporarily.

Would using VPN or TOR be possible, guess it must if they work in China?
It will work and it will not work. The simple answer is that it will be constantly changing, because it's a cat and mouse game. We simply don't know until it's implemented.
Don't assume that China will share their blacklist with Cambodia. The priorities are different and Cambodia will have its hands full blocking in accordance to their own priorities. It would be devastating for China if their official blacklists leaked. They will never share that with Cambodia.
Realistically put Cambodia will have the means to block Tor, and VPN will mostly be a children's game. There are several bypass techniques but it would be foolish to post them in public before the NIG has been put in place. We will simply have to find ways to adapt to the situation when it's reality.
While Cambodia has the means to block Tor, Tor also has the means to circumvent blocks. VPN providers are sitting ducks and most of them are not interested in helping you bypass national level censorship. They want the easy low maintenance customers who do some filesharing or want to bypass geolocation restrictions to watch some Netflix documentary.
