Exhibit 99.1

American Oriental Bioengineering Inc. Receives NYSE Notice of Delisting or Failure to Satisfy a Continued Listing Rule or Standard

NEWARK, N.J., April 6, 2012 /PRNewswire-Asia-FirstCall/ -- American Oriental Bioengineering, Inc. (NYSE: AOB) (the "Company") today announced that the New York Stock Exchange (the "NYSE") has notified the Company that it is not in compliance with NYSE rules due to the Company's failure to timely file its Annual Report on Form 10-K with the Securities and Exchange Commission.

Under NYSE rules, when a Company does not comply with annual report filing requirements, the NYSE allows a company an additional six months to file its annual report in order to regain compliance.  In the case of the Company, the annual report would be due on or before October 29, 2012.  If the Company fails to file its annual report within that time period, the NYSE may, in its sole discretion, allow the Company's securities to remain listed for up to an additional six months or may, in its sole discretion, commence suspension and delisting procedures. 

As previously announced, during the performance of the annual audit of the Company's financial statements for the fiscal year 2011, the Company's auditors, Ernst & Young Hua Ming's (E&Y), noted certain inconsistencies.  As a result, the Audit Committee has commenced an independent investigation into the matters identified by E&Y.  Although the Company cannot know at this time how long the investigation will take, the Company will endeavor to file the Form 10-K as soon as possible upon the completion of the investigation.
