I,
      Wenjun
      Jiao, Chief Financial Officer of Tiens Biotech Group (USA), Inc. (the

1.
      I have
      reviewed this annual report on Form 10-K for the fiscal year ended December
      31,
      2007, of the Registrant.

      Based
      on my knowledge, this report does not contain any untrue statement of a material
      fact or omit to state a material fact necessary to make the statements made,
      in
      light of the circumstances under which such statements were made, not misleading

      for, the periods, presented in the report.

      Registrant's other certifying officer and I are responsible for establishing
      and
      maintaining disclosure controls and procedures (as defined in Exchange Act

      defined in Exchange Act Rules 13a-15(f) and 15d-15(f)) for the Registrant and
      have:





|a. | Designed
              such disclosure controls and procedures, or caused such disclosure
              controls and procedures to be designed under my supervision, to ensure
              that material information relating to the Registrant, including its
              consolidated subsidiaries, is made known to me by others within those
              entities, particularly during the period in which this report is being
              prepared;
|-- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------




|b. | Evaluated
              the effectiveness of the Registrant's disclosure controls and procedures
              and presented in this report our conclusions about the effectiveness
              of
              the disclosure controls and procedures, as of the end of the period
              covered by this report based on such evaluation;
              and
|-- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------




|c. | Disclosed
              in this report any change in the Registrant's internal control over
              financial reporting that occurred during the Registrant's most recent
              fiscal quarter (the Registrant's fourth fiscal quarter in the case
              of an
              annual report) that has materially affected, or is reasonably likely
              to
              materially affect, the Registrant's internal control over financial
              reporting; and
|-- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------




5.
      The
      Registrant's other certifying officer and I have disclosed, based on our most
      recent evaluation of internal control over financial reporting, to the
      Registrant's auditors and the audit committee of the Registrant's board of
      directors (or persons fulfilling the equivalent function):





|a. | All
              significant deficiencies and material weaknesses in the design or
              operation of internal control over financial reporting which are
              reasonably likely to adversely affect the Registrant's ability to record,
              process, summarize and report financial information;
              and
|-- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------




|b. | Any
              fraud, whether or not material, that involves management or other
              employees who have a significant role in the Registrant's internal
              control
              over financial reporting.
