These consultancies thrived by providing investors - from global hedge funds to private equity firms - access to industry experts and investigators who could obtain valuable corporate information. One private credit investor who used to join Capvision's calls with "industry experts" said clients did not want to pay top dollar for easily available public information. Many China-based consultancy firms also outsourced on the ground investigations to local contractors. Even before the latest raids on consultancy firms, some due-diligence firms were warned to stay away from Xinjiang related projects, sometimes by security authorities, according to industry sources. China denies abuses in Xinjiang, a major cotton producer that also supplies much of the world's materials for solar panels.
