Russian voices still reverberate at the former Russia House in Davos much like in the past, only this time they are not reaching out to prospective investors. Instead, they are the voices of Russian soldiers talking to people back home about their military activities in Ukraine. Rechristened the "Russia War Crimes House," the Russian residence in the Swiss Alpine town since 2018 is being used by a Ukrainian charity to expose Russia's war crimes in Ukraine. "This is an example of what Russia has done to itself by becoming a state of war criminals," Ukrainian President Volodymyr Zelenskiyy said during his virtual address to Davos participants on Monday, referring to the renaming of the Russian house. The Russia House, organized by the Kremlin-backed Roscongress Foundation, was a key constituent of Russia's sales pitch to the global investor community in Davos. In 2020, the last time the Davos crowd convened in person, the house hosted more than 2,000 participants from 85 countries, including US billionaire Ray Dalio and Qatari royal family member Sheikh Ali Alwaleed Al Thani. This year, the building has been rented by Ukraine after the World Economic Forum decided not to invite Russian officials and business leaders to Davos in response to the war. The house, located prominently on the Davos Promenade, features an exhibition where thousands of photographs of Ukrainian victims of the war have been edited together into a film with voices of Russian soldiers playing in the background. "This used to be the place where Russia presented itself to the world. For us, it's incredibly important that we speak here about the reality of Russia," Bjorn Geldhof, one of the curators of the exhibition, said. "What we have shown is not only how gruesome it is, but how enormous it is, how many actions, how many crimes were committed against Ukrainians. Every body you see is a citizen who was shot and killed by a Russian soldier," the artistic director of the PinchukArtCentre in Kyiv told DW. Ukraine is being represented by its biggest-ever official delegation in Davos. A host of events and sessions have been dedicated to the war-ravaged country, which Ukrainian delegates and business leaders hope will exhort governments and corporations to continue supporting their country. "If we tell the story of this tragedy as loud and wide as possible, it will save some lives. We hope it will prompt politicians around the world to send weapons [to Ukraine] quicker, and impose even more severe sanctions [on Russia]," Ukrainian billionaire Victor Pinchuk, whose eponymous foundation is behind the Russia War Crimes House, said during the exhibition's opening ceremony on Monday. For many attending the Davos summit, the WEF's decision to ban Russia is a welcome one. "I do not think that at this particular point you can engage in any meaningful dialogue with Russia. We have tried that," Ivanna Klympush-Tsintsadze, a Ukrainian lawmaker, told DW. "I think lessons have to be learned. Russia has to be defeated and ensure that it is weakened to the point that it is not capable of waging another war against anybody."

Whether it was flying in Olympic figure skating stars for a private show or organizing a concert by Enrique Iglesias, the flashy high rollers did everything to serenade the world's elite. Looking beyond parties and investment deals, the Davos summit has had a key place in Russian history. In 1996, it was here in the Swiss Alps that a group of Russian oligarchs came up with the "Davos Pact" to prevent what seemed like a certain defeat for President Boris Yeltsin in his reelection bid. Over a decade later, then-First Deputy Prime Minister Dmitry Medvedev attended the global platform, which was widely seen as the unveiling of President Vladimir Putin's successor to the world. Putin, who is known to share a decades-long personal relationship with WEF founder Klaus Schwab, has addressed the forum twice, including last year. But Russia's tryst with Davos, which withstood Western sanctions following the annexation of Crimea in 2014, changed dramatically following the invasion of Ukraine in February. Within days, Schwab condemned the Russian aggression and atrocities. The WEF froze all its ties with Russian oligarchs and entities, including lucrative business partnerships with some of them. "We would have liked to build bridges by facilitating dialogue. But we clearly have a situation that one nation or one person doesn't want to engage in such a dialogue," Yann Zopf, head of media at WEF, told DW. "But should that situation change? The WEF will certainly be ready to play a facilitator and try to build those bridges." Edited by: Hardy Graupner
