Climate Change negotiations may go worse at UNFCCC COP 18 and beyond

During a recent communication with one of my professors at the University of California, Berkeley, I learned that China may take very different position during UNFCCC 18 negotiation in Doha, especially with regard to net emission of CO2 from major economies. He believes that this will be a new logic that attributes end user as the emitter of the unit carbon released to atmosphere while producing such goods and services. Since more than 70% of Chinese products are consumed in US, UK, EU, Japan, Korea and other members of the BRIC group, China may argue that it is not responsible for that extra 70% emission which is taking place to serve demand abroad. What do you think will convince China to withdraw this logic? or any thoughts as counterarguments? Do you sill see clime change negotiations well in track?
