Even though you really can't draw any laws from history, the historical predecent is usually at least telling. Tell us how many times civilian bombings have crushed the enemy morale?
2) You don't need to level a whole city with a nuke, radiation is good enough to finish the job, no matter how "clean" (and chinese nuclear missiles aren't being copies of 1960s US tech) they are.
If you use one nuke per city, you have to airburst it - actually, you should always airburst when engaging building complexes, much more destructive power that way - but way less fallout. Then you don't get too much of radiation, really. You could get a lot radiation by making the bomb a neutron bomb, when it would turn into relatively weak tactical nuke. Destrying civilian centers requires more than one nuke, and rendering the ground uninhabitable for longer time requires quite a bit of excessive ground-turning.
3) Take out the cold war nuclear strategy as you haven't an ocean between you.
In case of conflict between Russia and China it would be a total extermination war once nukes are fired.
Nuclear exchange strategy is pretty universal. The response time varies - if China launched a first-strike, Russia would have less time to decide their course of action than in US-Russia lobmatch.
Both sides gets the effect as winds have a nasty tendency to transport radioactive dust and other not so nice stuff around (Chernobyl anyone?) and so you can say goodbye to both countries logistical infrastructure, making the war a fight on terms of raw power between the remnants of both armies.
You need pretty hardcore nuclear wasteland for the winds to be some poisoned breath from hell over very long distances. Short distances yeah. Radioactive and poisonous dust is pretty heavy, and does not float over very long distances. The radioactivity itself is usually not the issue, but breathing heavy metals and other toxic instances.
So, in the unlikely case of war you have
a) conventional war, where China would win (at no small cost of course) over Russia (alone)
What would be the goals of China? Annex eastern Siberia? Doable. Get Russia surrender? Hmmm. The power point of Russian Federation is the western Russia, and the supply routes grow long. The toll on transportation capability would be enormous.
b) both sides are dead (MAD)
I guess not much would happen.
4) Tactical nukes? No one got tactical nukes except the US that is resurrecting them after getting out of the Moscow treaty (congratulations btw), we're talking about strategic ones here.
What, no tactical nukes? wtf
5) How can 300 nukes bring the world back?
a) you level out the most importan economic centers for 50 years
b) you poison air, land, water and food with radiation
c) you fry a good share of world's electric equipment
d) as there would be no organized government on large scale anymore = anarchy and no development [/B]

You have some pretty hardcore nukes there. Humanity has an incredible capabilty to repair damage and overcome.
Levelling out the most important economic centers, like New York, London, Berlin, Beijing and Tokyo - sure. Easy. I don't know who would do that though, but that's irrelevant. OK so now we have worldwide depression and something would propably happen.
Poisoning the air, land, water and food - with the same 300 nukes you have already used a part on grinding the major cities to dust? You can cause local famines (even on global economics the famines are for some incomprehensible reason local effects). Now you can scratch over at least 50 nukes, maybe even more.
EMP assaults? Go ahead, that's pretty good idea. They're repairable, though, and quite a significant amount of really important ones are hardened already.
As for the anarchy - someone will ALWAYS take control. Are you destroying all of the most important governments, along with good chunks of world's military power and so on, with the same 300 nukes you have already used to radiate food supplies (short-term), destroy major cities (geopolitical unforseemeable consequences) and cause EM pulses (nice). You have great strategical eye there.
Here's
everything you need to know about nuclear weapon effects. It's long, though, but very accurate.
