EXHIBIT 31

                      CERTIFICATION PURSUANT TO SECTION 302
                        OF THE SARBANES-OXLEY ACT OF 2002

I, Edward Miers, certify that:

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

     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 small business issuer as of, and for, the periods
          presented in this quarterly report;

     4.   I am responsible for establishing and maintaining disclosure controls
          and procedures (as defined in Exchange Act Rules 13a-15(e) and
          15d-15(e)) for the small business issuer and 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
               small business issuer, including its consolidated subsidiaries,
               is made known to us by others within those entities, particularly
               during the period in which this report is being prepared;

          (b)  Evaluated the effectiveness of the small business issuer
               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 small business
               issuer's internal control over financial reporting that occurred
               during the small business issuer's most recent fiscal quarter
               (the small business issuer's fourth fiscal quarter in the case of
               an annual report) that has materially affected, or is reasonably
               likely to materially affect, the small business issuer's internal
               control over financial reporting; and

     5.   The small business issuer's other certifying officer(s) and I have
          disclosed, based on our most recent evaluation of internal control
          over financial reporting, to the small business issuer's auditors of
          the small business issuer's board of directors (or persons performing
          the equivalent functions):

          (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 small
               business issuer'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 small business
               issuer's internal control over financial reporting.
