High in the Bavarian Alps, at a special security session, G7 leaders set out to devise an ambitious plan to sanction Russian energy sales.

While the exact details have yet to be determined, the price cap would be chosen in close collaboration with international allies. What level, if any, should be set for both oil and gas?
