EXHIBIT 31.2


                                  CERTIFICATION



     I, Winston Yen,  Chief  Financial  Officer of Chilco River  Holdings  Inc.,
certify that:

     1. I have reviewed this quarterly report on Form 10-QSB;

     2. Based on my knowledge, this quarterly 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  with respect to the period covered by this quarterly
report;

     3. Based on my knowledge,  the financial  statements,  and other  financial
information  included in this quarterly  report,  fairly present in all material
respects the financial  condition,  results of operations  and cash flows of the
registrant as of, and for, the periods presented in this quarterly report;

     4. The  registrant's  other  certifying  officers and I are responsible for
establishing and maintaining  disclosure  controls and procedures (as defined in
Exchange Act Rules 13a-15(e) and 15d-15(e)) for the registrant and we have:

     (a)  designed  such  disclosure  controls  and  procedures,  or caused such
          disclosure   controls  and   procedures  to  be  designed   under  our
          supervision,  to ensure  that  material  information  relating  to the
          registrant,  including its consolidated subsidiaries, is made known to
          us by others within those entities,  particularly during the period in
          which this quarterly 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  registration'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  officers 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  registrant's  board of
directors (or persons performing 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
          controls over financial reporting.
