Maybe that's true, but isn't this the exact same argument used by Americans: "Why should I stop driving my SUV, when China will burn that gas anyway?"

False Equivalence

When the gas is gone those SUVs will simply stop working. When the fish are gone large populations of people will not have sufficient food to eat.

moreso, "why should the government [because private industry would anyway with the prices] invest in solar and wind instead of coal, China will burn the coal anyway"

SUVs/Trucks -> Midsize by individuals driving 95% < 30 miles is less meaningful change than many other changes. (especially considering the future of the SUV is hybrid/electric). The math changes if the question becomes, instead of size of car, reducing the car/household for walking, biking, or carpooling.
