In 2011, activist short-seller Carson Block and his research firm, Muddy Waters Research, accused Sino-Forest, a Toronto-listed Chinese forestry company, of overstating its timber holdings. The allegations centered on whether the company had misrepresented the scale and ownership of its forest assets, information that was material to investors assessing Sino-Forest’s value. Block’s campaign made him widely known and was later featured in the 2017 documentary *The China Hustle*.
Sino-Forest ultimately entered Canadian bankruptcy protection after Block’s disclosures, although the supplied source does not provide a court finding, a precise date for the filing, or financial figures quantifying the alleged misstatements. The episode became an early example of the risks associated with North American listings of Chinese companies and the role short-sellers can play in exposing alleged accounting irregularities. By April 2021, the source stated that eight companies Block had exposed as fraudulent had been delisted and two others had settled charges with regulators; in 2024, U.S. authorities closed civil and criminal probes into Block’s own activities without taking action.
