Form 20-F for the year ended December 31, 2019

Item 15. Controls and Procedures
A. Disclosure Controls and Procedures
B. Management's Report on Internal Control over Financial Reporting, page 96

2.       We note under Disclosure Controls and Procedures you state    Our
principal executive
         officer (CEO) and our principal financial officer (CFO), after
evaluating the
         effectiveness of our disclosure controls and procedures (as defined in
Exchange Act
         Rule 13a-15(e)) as of the end of the period covered by this annual
report, have concluded
         that, as of such date, our internal control over financial reporting
was effective   . We
         also note under Internal Control over Financial Reporting you did not
provide
         an assessment from management as to the effectiveness of internal
control over financial
         reporting as of December 31, 2019. Please be advised, as required by
Item 15(a) and Item
         15(b)(3) of Form 20-F -K, management is required to provide separate
conclusions as to
         the effectiveness of Disclosure Controls and Procedures and the
effectiveness of Internal
         Control over Financial Reporting as of December 31, 2019. Please amend
your Form 20-
         F to clarify your disclosures and to fully comply with the
requirements of Item 15 of Form
         20-F.
D. Changes in Internal Control Over Financial Reporting, page 97

3.       We note under Changes in Internal Control over Financial Reporting you
state    As of
         December 31, 2019, management of the Company believes it has complied
with the
         remediation plans identified in the Annual Report on Form 20-F for the
year ended
         December 31, 2018, and the Company has completed the process of
implementing
         mitigating control measures to remedy in full the material weaknesses
and significant
         deficiencies identified   . However, we also note you state    There
have been no changes in
         the Company   s internal control over financial reporting during the
year ended December
         31, 2019, that have materially affected, or are reasonably likely to
materially affect, the
         Company   s internal control over financial reporting   . It is not
clear to us how these two
         statements can both be accurate. To the extent remediation plans were
completed and
         implemented, it appears to us this would indicate changes did occur.
In addition, we note
         your disclosure on page F-46 that indicates remediation efforts
continue. Please clarify
         and correct these disclosures and ensure you fully comply with Item
15(d) of Form 20-F.

Consolidated Financial Statements
Consolidated Statements of Changes in Equity, page F-6

4.       Please present statements of changes in equity for each year in the
three years ended
         December 31, 2019 as required by Items 8 and 18 of Form 20-F.

statements

5.       We note the value of your coke inventory declined year over year based
on the price per

the methods
         and sources you use to determine the value of your coke inventory.
15. Income Taxes, page F-34

6.       Given the substantial fluctuation in your effective income tax rate,
please provide a more
         robust explanation of the specific factors that contributed to
variations. In this regard,
         please clarify your disclosure that 2019 includes taxes and expenses
"which are covered
         by various companies of the Group and are derived by agreements
between the companies
         and SAT during 2019". Please more fully address if and how these
agreements are related
         to the tax audits disclosed in note 23(l) and more fully explain the
current status of the tax
         audits, including the amount and expected timing of any reasonably
possible additional
         losses.
       In closing, we remind you that the company and its management are
responsible for the
accuracy and adequacy of their disclosures, notwithstanding any review,
comments, action or
absence of action by the staff.
