Of France and Shouldn't China care more about the NPT and Iran?

Consider during the time leading up to the Second Iraq War that one of the leading critics against the war was none other than that western european country with the largest oil interests in Iraq -- France, a country that hailed herself as being multilateral at the time (and when Freedom Fries were apparently the fashion... I missed out on this trend as I was overseas).

But, we see a similar situation happening again in Iran with Chinese intransience over implementing another round of sanctions. You see, Iran signed a deal with China shortly after the U.S. invaded Iraq:

Under a memorandum of understanding signed Thursday, Sinopec Group will buy 250 million tons of liquefied natural gas over 30 years from Iran and develop the giant Yadavaran field.

Iran is also committed to export 150,000 barrels per day of crude oil to China for 25 years at market prices after commissioning of the field ("China, Iran sign biggest oil & gas deal" | China Daily)

Here's another deal signed last year. It's unfair to say that the U.S. chases after oil when China and France (the last time around) are stubbornly refusing to sanction a country, which regularly claims it will destroy another country (Israel) and denies the Holocaust ever happened,  that -- by any interpretation is bent on getting the bomb(consider that the U.S. + the 3 major EU countries are on the same page now). I feel it's a bit absurd that the U.S. gets singled out when there's no other country in the world that is willing to take on Iran. I thought China recently hailed its system of government as being able to complete tasks in a fashion that democratic governments could not...

Then, why is there so much reluctance on the part of China to look ahead of its near term interests (oil & natural gas) and not ponder about what will happen in say thirty years or so... when if things start getting rough... it looks like the United States will hide behind two oceans with a nuclear missle shield, whereas China will be bordering possibly a nuclear Korea(s), Japan, India, Pakistan, Iran, Burma(!), Russia, etc etc... The breakdown of the NPT will hurt China more than anybody else...
