Leaders of Western governments and chief executives of the biggest Western corporations came to the event to hold negotiations, strike deals and meet with Russian President Vladimir Putin. All this became history following Russia's invasion of Ukraine. The main theme of the forum this year was "game over" for Western rules. The focus was on new investors, and 17,000 participants from 130 countries attended. But energy deals were scant and some signs of discontent with the trajectory of the energy sector were voiced by Russia's biggest oil producer.
