EXHIBIT 31.1

CERTIFICATION

I, Tom Yu Liu, Chief
Executive Officer and Acting Principal 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.
