                                                        to provide prominent

                                                        Kong. Your cover page

                                                            Make clear whether
these risks could result in a material change in your operations
                                                             and/or the value
of your ADSs, could significantly limit or completely hinder your
                                                             ability to offer
or continue to offer securities to investors, and could cause the value
                                                             of such securities
to significantly decline or be worthless.

               Address how recent statements and regulatory actions by China
s government, such
             as those related to the use of variable interest entities and data
security or anti-
             monopoly concerns, has or may impact the company   s ability to
conduct its business,
             accept foreign investments, or list on an U.S. or other foreign
exchange.
         Additionally, your prospectus summary should be revised to address in
greater detail, but
         not necessarily be limited to, the risks highlighted on the prospectus
cover page.
2.       We note your response to prior comment 2 and we reissue in part. On
the cover page
         itself, please clearly disclose how you will refer to the holding
company and subsidiaries
         when providing the disclosure throughout the document so that it is
clear to investors
         which entity the disclosure is referencing and which subsidiaries or
entities are conducting
         the business operations. To that end:
             Clearly disclose that investors in the ADSs are purchasing equity
securities of
              LianBio, a Cayman Islands exempt holding company, rather than
equity securities of
              your subsidiaries that have substantive business operations in
the U.S. and China.
             Please identify the names of the subsidiaries that conduct your
operations in the U.S.
              and China as you have in your organization structure chart, and
indicate whether in
              the prospectus you will refer to LianBio and its subsidiaries,
including but not limited
              to its operating company subsidiaries, as a group.

Prospectus Summary, page 1

3.       We note your response to prior comment 4 and we reissue in part. We
note that you have
         revised your disclosure on page 8 to describe potential permissions
required from PRC
         entities to issue your ADS securities to foreign investors. Please
further revise your
         prospectus summary to disclose each permission that you or your
subsidiaries are required
         to obtain from Chinese authorities to operate your business, and
affirmatively state
         whether you and your subsidiaries have received each such requisite
permissions and
         whether any such permissions have been denied.
4.       We note your response to prior comment 5 and we reissue in part. In
the prospectus
         summary itself, please expand your disclosure regarding how cash is
transferred through

have occurred
             between the holding company and its subsidiaries during the time
period covered by
             your registration statement, and direction of transfer. If no such
flows or transfers
             occurred, please so state.
             Quantify any dividends or distributions that a subsidiary has made
to the holding
             company and which entity made such transfer, and their tax
consequences. Similarly
             quantify dividends or distributions made to U.S. investors, the
source, and their tax
             consequences. If no such dividends or distributions have been
paid, please so state.
             Describe any restrictions on foreign exchange and your ability to
transfer cash
             between entities, across borders, and to U.S. investors.
             Describe any restrictions and limitations on your ability to

5.       We note your response to prior comment 9 and we reissue in part. In
your risk factors
         summary, please expand your disclosure of the risks that your
corporate structure and
         being based in or having the majority of the company   s operations in
China and Hong
         Kong poses to investors. In particular, describe the significant
regulatory, liquidity, and
         enforcement risks with cross-references to the more detailed
discussion of these risks in
         the prospectus. For example, specifically discuss:
             Risks arising from the legal system in China, including risks and
uncertainties
              regarding the enforcement of laws and that rules and regulations
in China can change
              quickly with little advance notice;
             The risk that the Chinese government may intervene or influence
your operations at
              any time, or may exert more control over offerings conducted
overseas and/or foreign
              investment in China based issuers, which could result in a
material change in your
              operations and/or the value of your ADSs; and
             Acknowledge any risks that any actions by the Chinese government
to exert more
              oversight and control over offerings that are conducted overseas
and/or foreign
              investment in China-based issuers could significantly limit or
completely hinder your
              ability to offer or continue to offer securities to investors and
cause the value of such
              securities to significantly decline or be worthless.
Our Pipeline, page 2

6.       We note your response to prior comment 7 and we reissue in part. With
regard to
         NBTXR3, we note your response that your response letter states that
the Company is not
         currently pursuing this candidate for the treatment of STS "in China,"
whereas your
         revisions to footnote 2 to the pipeline table states: "At present,
[the Company is] not
         pursuing NBTXR3 in relation to this soft tissue sarcoma indication."
As it does not
         appear to be otherwise addressed in your prospectus disclosures,
please confirm whether
         or not the Company is currently pursuing NBTXR3 for the treatment of
STS in any of its
         other licensed territories in the world. We reiterate that if the
Company will not be
         involved in the further development or commercialization of NBTXR3 for
STS in its
         licensed jurisdictions, it would appear that this program is not
sufficiently material to your
         operations to warrant highlighting it in the pipeline table. Please
explain in your response
         why you believe it is appropriate to include NBTXR3 for STS in the
pipeline table,
         making clarifying revisions to your narrative disclosures throughout
the registration
         statement as appropriate, or remove.

7.       We note your response to prior comment 13 and we reissue in part.
Please further revise
         your disclosure to:
             Separately highlight as a risk factor, under appropriate caption,
that the Chinese
             government may intervene or influence your operations at any time,
which could
             result in a material change in your operations and/or the value of
your ADSs.

                Also, given recent statements by the Chinese government
indicating an intent to exert
              more oversight and control over offerings that are conducted
overseas and/or foreign
              investment in China based issuers, acknowledge the risk that any
such action could
              significantly limit or completely hinder your ability to offer or
continue to offer
              securities to investors, and cause the value of such securities
to significantly decline

Research and Development Expenses, page 122

8.       We note your response to comment 14. Your disclosure on page 123
indicates most of
         your research and development expense relates to licensing fees.
Please provide a
         breakdown of licensing fees by the the programs described on page 129.

Our strategy to seek regulatory approval of NBTXR3 in China, page 150

9.       We note that you have revised your pipeline disclosure to discuss your
estimates of the
         addressable market for various product candidates. For instance, we
note the following
         statement on page 150 regarding NBTXR3: "We believe NBTXR3 has the
potential to
         be used in the treatment of up to 925,000 patients in China each year
across our current
         potential solid tumor target indications, including an estimated
25,000 patients with
         locally advanced head and neck cancer, up to 150,000 patients with
other solid tumors
         (with or without additional chemotherapy), and up to 750,000 patients
in combination
         with radiotherapy and immunotherapy." Please expand this and all
similar disclosures to
         describe how you developed these beliefs and estimates, and provide
the sources upon
         which you are basing your calculations as well as any material
assumptions and
         limitations associated with your estimates.
Nanobiotix License, Development and Commercialization Agreement, page 171

10.      With respect to the Nanobiotix Agreement, we note your reference on
pages 170-171 of
         the amendment to "tiered low double-digit royalties." Please revise to
narrow the royalty
         range disclosed for this agreement to no more than ten percentage
points.
Note 3. Material Agreements, page F-16

11.      We note your response to comment 22. With respect to the conversion of
Myokardia
         warrants and Tarsus warrants, the conversion would be calculated based
on the fair market
         value of Lian Cardivascular, Lian Bio and the appreciation of the
value in the Lian
         Ophthalmology, respectively. You also state that the QED warrants may
be converted into
         ordinary shares of the Company. Please address the following:
             As the warrants have a conversion feature to convert from shares
of a subsidiary of
             the company into the shares of the Company, please provide us a
detailed analysis of
             why you believe the conversion features for your agreements is
clearly and closely

              related to the host instrument.
                Explain why you believe the settlement amount is for a fixed
number of shares. Refer
              to ASC 815-15-25-1c.
                Disclose the terms of the conversion feature of the QED
warrants into the Company's
              common stock.
                For the MyoKardia warrants, you disclose on page F-16 two
different ways the
              warrants may convert into the Company's common stock. Please
clarify which
              methodology is appropriate or clarify how the two methodologies
are used to
              determine the conversion rate into the Company's common stock.
                For all of your agreements, disclose the number of shares of
the Company's common
              stock the warrants could convert into at the end of each period
presented.
                We acknowledge your response to the third bullet of comment 22.
In order for us to
              understand your conclusion that the warrants are indexed to the
Company's stock,
              please tell us the nature of the operations of Lian
Cardiovascular and Lian Oncology
              and why you believe, if such is the case, that these entities
represent substantive
              subsidiaries. Refer to ASC 815-40-15-5C. In this regard, we note
in your response
              that the warrants issued to purchase shares of Lian Oncology were
issued on the same
              date as the Seed Funding, which appears to imply Lian Oncology
was recently
              formed and not a substantive subsidiary. In addition, clarify why
you believe the
              warrants to purchase 170,000 ordinary shares in Lian
Cardiovascular, valued at $33.8
              million, is an appropriate valuation in relation to Lian
Cardiovascular's operations.
              Tell us when Lian Cardiovascular was formed and the extent that
Lian
              Cardiovascular contributes to your results of operations. Tell us
how the value of the
              warrants compares to the total enterprise value of the Company.
12.      For each agreement discussed in Notes 3 and 12 in which milestone
payments are payable,
         provide a breakdown of the amount of payments due for each type of
milestone (e.g.
         development, regulatory, and sales).
13.      Refer to your response to the last bullet of comment 20 with respect
to your Pfizer
         Strategic Collaboration discussed on page F-16. Please address the
following:
             Please help us understand why you believe the Pfizer agreement
does not represent a
              collaborative arrangement as defined under ASC 808-10-20. Based
on Exhibit 10.12,
              it appears that your collaboration agreement with Pfizer falls
under ASC 808. In this
              respect we note that Pfizer is providing funding for development
costs and actively
              participates in the joint steering and collaboration committees.
We also note that
              Pfizer has certain Opt-In and Right of first negotiation rights
discussed in Articles 2
              and 3 of the agreement and Pfizer has the right to a license for
all Inventions invented
              or otherwise developed or generated jointly by both Parties as
discussed in Article 6.
             ASU 2018-18 discusses certain transactions between collaborative
participants that
              should be accounted for as revenue under ASC 606. Please clarify
why your
              collaborative arrangement does not fall under ASC 606, in which
case it would
              appear the payments would be recorded as deferred revenue until
the qualifying
              expenses have been incurred.

             You appear to be an early stage biotech in which research and
development activities
           would be part of your ongoing major and central operations. Since
research and
           development activities appear to be part of your ongoing major and
central
           operations, it does not appear that recording the upfront payment as
a reduction of
           research and development is appropriate. Refer to 808-10-55-5 by
analogy. Please
           revise your policy or tell us why recording the amount as
contra-research and
           development expense is appropriate.
