With the challenges of deepness and complex geology, China has no choice on shale gas but to seek foreign help
FT story on how "China opens shale gas exploration to foreign joint ventures."
It's described as a "milestone policy change that will allow foreign energy companies to play a greater role in developing China's rich potential reserves of shale gas."
China has all the same ambitions as the US: reduce dependency on foriegn sources of coal and oil, plus simply move "down" the hydrocarbon chain to less CO2 emissions.
The irony: to escape one form of foreign dependence is to invite another.
