Perhaps he is saying that the OPEC partners shouldn't be expected to cut their production in order to keep prices high for the competition. If all players cut production by 10% this might be perceived as being more fair than asking OPEC to cut by 20% while everyone else pumps at capacity.
As things stand high cost oil may simply close up shop & everyone will learn to live without tar-sands, shale, Arctic or deepwater production. I've heard that Russia is fine with cheap oil and a low Ruble but that Canada, Venezuela & American dreams of Oil Independence will crash hard.
China's financial backing of Russia disrupts any dreams of "breaking" Russia as the Soviets were broken by Saudi/American oil price manipulation in the mid 80's. Saudi oil will continue to be priced and bought with American dollars, but Russian oil, extracted in Rubles and sold to BRICS in local currencies opens a new avenue for energy hungry nations to explore.
Exported American gas can never compete with piped gas because of the huge costs of compressing/decompressing. The only markets available are island nations or those willing to sacrifice their competitiveness for ideological reasons. The EU did a quick about face re. South Stream, although that ship has probably already sailed, and those that believe they will willingly pay much more for American LNG than cheap Russian piped gas must believe that Merkel's phone calls contain some really explosive messages.
Russia will have a few rough years while businesses pay off dollar debts, then, baring WWIII, the Sino-Russian century begins (as long as climate change doesn't toss over the chess board).
