LETTER FROM THE BOARD

2. PROPOSED GENERAL MANDATES TO BUY BACK SHARES AND TO ISSUE SHARES

A general mandate was granted to the Board to exercise the power of the Company to buy back Shares at the last annual general meeting of the Company held on 25 May 2020. Such mandate will lapse at the conclusion of the forthcoming AGM. Therefore it is proposed that a fresh general mandate be granted to the Board to buy back Shares in the Company with an aggregate number of Shares not exceeding 10% of the total number of Shares in issue.

An explanatory statement, as required by the Listing Rules to be sent to the Shareholders in connection with the proposed ordinary resolution set out in item 5 of the Notice of AGM for the approval of the renewal of the general mandate for buy-back of Shares, is set out in Appendix I to this circular.

A general mandate was granted to the Board to exercise the power of the Company to issue Shares at the last annual general meeting of the Company held on 25 May 2020. Such mandate will lapse at the conclusion of the forthcoming AGM. Therefore it is proposed that a fresh general mandate be granted to the Board to issue Shares as more details are set out in item 6 of the Notice of AGM.

A resolution as set out in item 7 of the Notice of AGM will also be proposed at the AGM authorising the Directors to increase the maximum number of new Shares which may be issued under the general mandate for the issuance and allotment of Shares by adding to it the number representing the aggregate number of Shares bought back pursuant to the Buy-back Mandate.

3. PROPOSED RE-ELECTION OF DIRECTORS

Pursuant to the Articles of Association, Mr. Chen Zhongyue, Mr. Zhu Kebing, Mr. Wong Wai Ming and Mr. Chung Shui Ming Timpson (together, the ''Directors for Re-Election'') will retire at the AGM, and be eligible, offer themselves for re-election.

Mr. Chen Zhongyue has been acting as Executive Director & President of the Company since February 2021. Mr. Zhu Kebing has been acting as the Executive Director & Chief Financial Officer of the Company for approximately 3 years. Mr. Wong Wai Ming and Mr. Chung Shui Ming Timpson have been acting as an Independent Non-Executive Director of the Company for approximately 15 and 12 years respectively. During their tenure as Directors of the Company, they have not engaged in the daily administrative management of the Group. They have expressed objective views and exercised independent judgements in fulfilling their duties to the Company as Independent Non-Executive Directors, and they continue to demonstrate the ability to provide an independent, balanced and objective view to the affairs of the Company. They have provided excellent advice on the affairs of the Company from time to time which promoted and enhanced the management of the Company and standardised the corporate governance practice of the Company. In 2020, the Company was awarded a number of accolades, including it was voted as ''Asia's No. 1 Most Honored Telecom Company'' by Institutional Investor for five consecutive years and voted as ''Best Corporate Governance in Asia'' by FinanceAsia. Mr. Wong Wai Ming and Mr. Chung Shui Ming Timpson as the Independent Non-Executive Directors of the Company, have both confirmed to the Company that they are in compliance with the requirements of independence pursuant to Rule

3.13 of the Listing Rules (including the notes thereto) and have devoted sufficient time and attention to the affairs of the Company. The Company has conducted assessment on their independence, and is of the view that each of them complies with the guidelines on independence as set out in Rule 3.13

LETTER FROM THE BOARD

of the Listing Rules (including the notes thereto) and that Mr. Wong Wai Ming and Mr. Chung Shui Ming Timpson are considered as independent in accordance with the provisions of the guidelines. Meanwhile, the Company is of the view that Mr. Wong Wai Ming and Mr. Chung Shui Ming Timpson performed their fiduciary duties as well as devoted sufficient time and attention to the affairs of the Company. Mr. Wong Wai Ming has extensive experience in management and finance. Mr. Chung Shui Ming Timpson is serving as Independent Non-Executive Director of eight listed companies (including the Company). He has extensive experience in management, finance and education. In particular, his directorship experiences in other listed companies are beneficial in equipping him with accumulative knowledge and experience on matters such as the latest developments and trends in directors' duties, listing rules requirements, regulatory focus and compliance. Please refer to Appendix II for details. According to the Company's nomination policy, the Nomination Committee reviewed the Board's structure, size and composition with due regard to the benefits of diversity on the Board, and was of the view that the re-election of the four Directors to be Directors of the Company can continuously enhance the level of management of the Company and keep the diversity of Board composition (including but not limited to age, cultural and educational background, professional experience, skills, knowledge and duration of service) through leveraging their professional experience and knowledge. It can also promote the objective decision-making of the Board and contribute to the full and impartial supervision of the management of the Company in accordance with the interests of the Company and the Shareholders as a whole. The Board accepted the opinion and recommendation by the Nomination Committee. The Board recommended the four directors to be re-elected at the AGM.

The biographies of the proposed Directors for Re-Election are set out in the Appendix II to this circular.

Except as noted in the biographies, (i) the Directors for Re-Election have not held any other directorships in any listed public companies in the last three years nor any post in an affiliated company of the Group; and (ii) none of the Directors for Re-Election is connected with any Directors, senior management, substantial shareholders (as defined under the Listing Rules) or controlling shareholders of the Company.

As at the Latest Practicable Date, Mr. Chung Shui Ming Timpson had personal interests in 6,000 Shares of the Company, representing approximately 0.0000% of the issued shares of the Company. Save for the above, the Directors for Re-Election did not have any interest in the Shares of the Company within the meaning of Part XV of the Securities and Futures Ordinance.

Please refer to the 2020 Annual Report of the Company for details of the remuneration of Mr. Zhu Kebing, Mr. Wong Wai Ming and Mr. Chung Shui Ming Timpson in 2020. Mr. Chen Zhongyue has been appointed as a Director of the Company in February 2021. The terms of services agreed between the Directors for Re-Election and the Company neither specify the length of service nor require the Company to give more than one year's advance notice or to make payments equivalent to more than one year's remuneration to terminate the service (other than statutory compensation). However, the Directors are subject to retirement at annual general meetings in accordance with the Articles of Association. The proposed remuneration package of directors of the Company will be determined by the Remuneration Committee, subject to approval by the Board and in compliance with applicable laws, regulations and policies, and taking into account the responsibilities of such person in the Company, his experience and performance as well as the prevailing market conditions. The Company will disclose as and when appropriate once the proposed remuneration packages for such persons have been determined.

LETTER FROM THE BOARD

Save as disclosed in this circular, each of the Directors for Re-Election has confirmed that there is no other matter that needs to be brought to the attention of the Shareholders of the Company and that there is no other information to be disclosed pursuant to Rule 13.51(2) of the Listing Rules.

4. PROPOSED APPOINTMENT OF AUDITORS

As the Company is an indirect subsidiary of Unicom Group, which is a state-owned enterprise under the supervision of the State-owned Assets Supervision and Administration Commission of the State Council. Pursuant to the relevant regulations issued by the Ministry of Finance of the People's Republic of China and the State-owned Assets Supervision and Administration Commission of the State Council, there are restrictions in respect of the years of audit services that an accounting firm can continuously provide to a state-owned enterprise and its subsidiaries. Considering the relevant regulations, the Board of the Company announces that KPMG and KPMG Huazhen LLP (together as ''KPMG'') will retire as auditors of the Group upon expiration of their current term of office at the close of the forthcoming AGM. The Board, as recommended by the audit committee of the Company, has resolved to propose to the Shareholders at the AGM to approve the appointment of Deloitte Touche Tohmatsu and Deloitte Touche Tohmatsu Certified Public Accountants LLP as the auditors of the Group for Hong Kong financial reporting and U.S. financial reporting purposes, respectively, for the year ending 31 December 2021, and authorise the Board to fix the remuneration of the auditors.

KPMG confirmed in writing that there were no matters in relation to the proposed change of auditors that need to be brought to the attention of the Shareholders. The Board has also confirmed that there were no disagreement or outstanding matters between KPMG and the Company and there were no other matters in relation to the proposed change of auditors that need to be brought to the attention of the Shareholders.

5. ANNUAL GENERAL MEETING

The AGM will be convened at 11 : 00 a.m. on 13 May 2021 at Four Seasons Grand Ballroom, Level 2, Four Seasons Hotel Hong Kong, 8 Finance Street, Central, Hong Kong and China Unicom Building, 21 Financial Street, Xicheng District, Beijing, P.R.C. concurrently by electronic means.

APPENDIX I EXPLANATORY STATEMENT OF SHARE BUY-BACK MANDATE

This explanatory statement contains all the information required under Rule 10.06(1)(b) of the Listing Rules and also constitutes a memorandum required under section 239 of the Companies Ordinance.

EXERCISE OF THE BUY-BACK MANDATE

The Directors believe that the flexibility afforded by the Buy-back Mandate would be beneficial to the Company. It is proposed that up to 10% of the total number of issued and outstanding Shares on the date of the passing of the ordinary resolution (subject to adjustment in the case of any subdivision and consolidation of Shares after the relevant general meeting) to approve the Buy-back Mandate may be bought back. As at the Latest Practicable Date, 30,598,124,345 Shares were in issue and outstanding. On the basis of such figure, the Directors would be authorised to buy back up to 3,059,812,434 Shares during the period up to the date of the next annual general meeting in 2022, or the expiration of the period within which the next annual general meeting of the Company is required by law to be held, or the revocation or variation of the Buy-back Mandate by an ordinary resolution of the Shareholders at a general meeting, whichever of these three events occurs first.

REASONS FOR BUY-BACKS

Buy-backs of Shares will only be made when the Directors believe that they will benefit the Company and its Shareholders. Such buy-backs may, depending on the market conditions and funding arrangements at the time, lead to an enhancement of the net asset value of the Company and its assets and/or its earnings per Share.

FUNDING OF BUY-BACKS

Buy-backs pursuant to the Buy-back Mandate would be financed entirely from the Company's available cash flow or working capital facilities. Any buy-backs will be made out of funds of the Company legally permitted to be utilised for such purpose in accordance with its Articles of Association and the laws of Hong Kong, including distributable profits. Under the Companies Ordinance, a company's distributable profits, in relation to the making of a payment by the company, are those profits out of which the company could lawfully make a distribution equal in value to the payment.

There might be a material adverse impact on the working capital or gearing position of the Company (as compared with the position disclosed in its most recent published audited accounts for the year ended 31 December 2020) in the event that the Buy-back Mandate is exercised in full.

However, the Directors do not propose to exercise the Buy-back Mandate to such an extent as would, in the circumstances, have a material adverse effect on the Company's working capital or gearing position, which in the opinion of the Directors are from time to time appropriate for the Company.

- 7 -

APPENDIX I EXPLANATORY STATEMENT OF SHARE BUY-BACK MANDATE

DISCLOSURE OF INTERESTS

None of the Directors, and to the best of their knowledge, having made all reasonable enquires, none of their close associates (as defined under the Listing Rules), have any present intention to sell Shares to the Company or its subsidiaries if the Buy-back Mandate is approved by the Shareholders. No core connected persons (as defined under the Listing Rules) of the Company have notified the Company that they (i) have a present intention to sell Shares to the Company or (ii) have undertaken not to sell Shares to the Company, if the Buy-back Mandate is approved by the Shareholders.

DIRECTORS' UNDERTAKING

The Directors have undertaken to the Stock Exchange that they will exercise the Buy-back Mandate in accordance with the Listing Rules and the applicable laws of Hong Kong.

SHARE BUY-BACKS MADE BY THE COMPANY

No buy-backs of Share have been made by the Company (whether on the Stock Exchange or otherwise) during the six months preceding the date of this circular.

TAKEOVERS CODE CONSEQUENCES

If as a result of a buy-back of Shares by the Company, a Shareholder's proportionate interest in the voting rights of the Company increases, such increase will be treated as an acquisition for the purpose of the Takeovers Code. As a result, a Shareholder, or group of Shareholders acting in concert, depending on the level of increase of its or their shareholding, could obtain or consolidate control of the Company and become obliged to make a mandatory offer in accordance with Rule 26 of the Takeovers Code.

As at the Latest Practicable Date, the immediate controlling shareholders of the Company are, Unicom BVI and Unicom Group BVI. Unicom BVI was recorded in the register required to be kept by the Company under Part XV of the Securities and Futures Ordinance as having an interest in 16,376,043,282 Shares, representing approximately 53.52% of the total number of issued and outstanding Shares as at that date. If the Buy-back Mandate is exercised in full, Unicom BVI will be interested in approximately 59.47% of the reduced number of issued and outstanding Shares based on Unicom BVI's interest in the issued and outstanding Shares and the total number of issued and outstanding Shares as at the Latest Practicable Date. Unicom Group BVI was recorded in the register required to be kept by the Company under Part XV of the Securities and Futures Ordinance as having a beneficial interest in 8,082,130,236 Shares, representing approximately 26.41% of the total number of issued and outstanding Shares of the Company as at that date. If the Buy-back Mandate is exercised in full, Unicom Group BVI will be interested in approximately 29.35% of the reduced number of issued and outstanding Shares based on Unicom Group BVI's beneficial interest in the issued and outstanding Shares and the total number of issued and outstanding Shares as at the Latest Practicable Date. Unicom BVI and Unicom Group BVI are presumed to be acting in concert with each other in respect of their aggregate 79.93% shareholding in the Company pursuant to class of the definition of ''acting in concert'' in the Takeovers Code as they are both ultimately controlled by Unicom Group. Therefore, as the aggregate shareholding in the Company held by Unicom BVI and Unicom Group BVI, being persons acting in concert, exceeds 50%, exercise of the Buy-back Mandate should, subject to the specific circumstances in the particular case, not result in a mandatory offer obligation upon Unicom BVI and Unicom Group BVI under Rule 26 of the Takeovers Code. Save as disclosed above, the Directors are not aware of any other consequences that may arise under the Takeovers Code as a result of a buy-back of the Shares.
