SINO-FOREST CONFIRMS ONTARIO SECURITIES COMMISSION INVESTIGATION

TORONTO, June 8, 2011 /PRNewswire/ - Sino-Forest Corporation (TSX: TRE) ("Sino-Forest" or the "Company"), a leading commercial forest plantation operator in China, today confirmed that the Ontario Securities Commission ("OSC") has opened an investigation.  The Company expected the OSC to take this step given its responsibility as the public regulator and the recent unusual trading activity and volatility in Sino-Forest's stock price and the allegations contained in Muddy Waters' report. The Company welcomes the OSC initiative and believes that the issues the OSC will seek to address will be consistent with the investigation commenced by an Independent Committee of the Board of Directors.

The Company has also formally requested that the Toronto Stock Exchange and the Investment Industry Regulatory Organization of Canada investigate the trading of the Company's shares by Muddy Waters, LLC and its principal Carson Block and anyone associated with these persons in advance of the issuance of the Muddy Waters' report.

The Company also intends to request an investigation by the Singapore Exchange Ltd in respect to the trading of the Company's bonds.
