CERTIFICATIONS

I, Victor Sun, certify that:

1.   I have reviewed this quarterly report on Form 10-QSB of East Delta
     Resources Corp. (formerly AVIC Technologies, LTD);

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; and

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 position, results of operations, and cash
     flows of the issuer as of, and for, the periods presented in this quarterly
     report.

4.   I am responsible for establishing and maintaining disclosure controls and
     procedures for the issuer and have:

          (i)       Designed such disclosure controls and procedures to ensure
                    that material information relating to the issuer is made
                    known to me, particularly during the period in which the
                    periodic reports are being prepared;
          (ii)      Evaluated the effectiveness of the issuer's disclosure
                    controls and procedures as of March 31, 2004; and
          (iii)     Presented in the report our conclusions about the
                    effectiveness of the disclosure controls and procedures
                    based on my evaluation as of the Evaluation Date;

5.   I have disclosed, based on my most recent evaluation, to the issuer's
     auditors and the audit committee of the board of directors (or persons
     fulfilling the equivalent function):

          (i)       All significant deficiencies in the design or operation of
                    internal controls which could adversely affect the issuer's
                    ability to record, process, summarize and report financial
                    data and have identified for the issuer's auditors any
                    material weaknesses in internal controls; and
          (ii)      Any fraud, whether or not material, that involves management
                    or other employees who have a significant role in the
                    issuer's internal controls; and

6.   I have indicated in the report whether or not there were significant
     changes in internal controls or in other factors that could significantly
     affect internal controls subsequent to the date of our most recent
     evaluation, including any corrective actions with regard to significant
     deficiencies and material weaknesses.
