The CCPA has a new piece by John Foster about Afghanistan that is very helpful in outlining the various (oil and) gas pipeline interests in and around that country. Very informative. It's not listed as Rabble News (yet) but perhaps it belongs here anyway.
Foster has written a number of pieces for the CCPA. Here's a list.
Novosti and/or Russia Today have a number of articles outlining the oil and gas competition from the Russian point of view and are good reading, if the search may take a bit, to round out one's understanding of the political economy in that part of the world.
