   1.                                                   We note that you have
various disclosures on pages 109 through 144 that appear to be
                                                        oriented towards the
disclosure requirements of Item 5 of Form 20-F. However, we do not
                                                        see among these
disclosures any tabulations of the accounts that comprise, or commentary
                                                        regarding, your
Statement of Financial Position which appears on page F-6.

                                                        The descriptions of
purpose and objectives included in the Item 5 disclosure requirements
                                                        include various
references to financial condition, as in expressing the need for disclosures
                                                        of your financial
condition, changes in financial condition, an explanation of factors that
                                                        have materially
affected or are reasonably likely to affect your financial condition,
                                                        quantitative and
qualitative descriptions of the reasons underlying material changes,
                                                        including material
offsetting changes within line items, associated statistical data, and

         material events and uncertainties that would cause reported financial
information not to be
         necessarily indicative of your future financial condition.

         Instruction 2 to Item 5 also stipulates that the discussion must focus
on the primary
         financial statements that are presented in the document.

         We believe that a discussion and analysis of the accounts that
comprise your Statement of
         Financial Position would be inherent in meeting these disclosure
requirements. Please
         expand your disclosures to cover these incremental details regarding
your financial
         condition as reflected in this statement to comply with Item 5 of Form
20-F.
4.6.1.8 Segment Performance and Analysis, page 127

2.       We note your discussion and analysis of segment activity, including
transportation and
         logistics, refining and petrochemicals, and electric power
transmission and toll roads
         concessions, in which you attribute changes in revenue, cost of sales,
operating expenses,
         and net income to a combination of several different factors.

         Item 5 of Form 20-F generally requires a quantitative and qualitative
description of the
         reasons underlying material changes, including material changes within
a line item that
         off-set one another, to the extent necessary for an understanding of
the business.

         Please quantify material changes that off-set one another within a
line item, to provide
         investors with better insight into the underlying reasons for the
changes that are reflected
         in your financial statements, as necessary to adhere to this guidance.
4.9 Financial Indebtedness and Other Contractual Obligations, page 139

3.       Please reconcile your disclosure on page 139, stating that you had
outstanding
         consolidated indebtedness of COP 23.5 billion at December 31, 2022,
with your
         disclosure in the table of contractual obligations on page 141,
indicating the outstanding
         balance of financial sector debt and bonds was COP 113,107.4 billion,
and disclosure
         about the composition of loans and borrowing in Note 20 on page F-77,
indicating that
         balance plus lease liabilities and related party debt was COP
115,134.8 billion at year-end.

         If this disclosure was intended to be a U.S. dollar equivalent, please
clarify the exchange
         rate that was utilized and the manner of selecting that rate, and
explain why it does not
         appear to agree with the rate utilized for convenience translations
disclosed on page 1.

         With regard to Table 64 on page 139, where you have listed various
issuances of debt
         along with the original currency denominated amounts, it would be
helpful to include
         another column showing the outstanding year-end balances in Colombian
Pesos, along
         with a summation that is reconciled to the corresponding amounts on
page F-77.

4.       We note that you identify six concessions or groups of concessions in
Colombia, Brazil,
         Chile, Peru and Bolivia, and provide a general indication of the
nature of the infrastructure
         involved, services to be provided, and the manner of compensation.

         However, your disclosures do not presently include the details
necessary to understand the

or rights to receive
         specified assets at the end of the concession period, renewal and
termination options, or
         rights and obligations regarding the maintenance of infrastructure.

         Please expand your disclosures as necessary to address the concerns
outlined above as
         required by IASB SIC-29; your descriptions of the arrangements should
inform readers in
         all of these respects, including the status of the arrangements,
timeframes in which the
         various obligations will be fulfilled, and material financial
implications.

       In closing, we remind you that the company and its management are
responsible for the

comments, action or
absence of action by the staff.
