Election of Languages and Means of Receiving Corporate Communications

China Unicom (Hong Kong) Limited (the "Company") is implementing arrangements to ascertain Shareholders' preference in receiving future Corporate Communications (i) in printed form (in English and/or Chinese) or (ii) through the Company's website.

INTRODUCTION

Pursuant to the Companies Ordinance, Listing Rules and Articles of Association, the Company is permitted to supply the Corporate Communications to Shareholders by electronic means or by posting them on the Company's website if Shareholders agree or are deemed to agree to this form of communication, provided that certain conditions are satisfied.

In support of environmental protection and for the purpose of saving printing and mailing cost, the Company is implementing arrangements to ascertain Shareholders' preference in receiving future Corporate Communications.

ARRANGEMENTS

1. The Company will send a letter setting out the detailed arrangements (the "First Letter") together with a reply form (the "Reply Form") to Shareholders to solicit their choice of either: (i) receiving the Corporate Communications in printed form, in English or in Chinese or in both languages (the "Printed Version"); or (ii) accessing the Corporate Communications through the Company's website (the "Electronic Version") instead of receiving the Printed Version. The First Letter and the Reply Form will not be sent to those Shareholders who are currently receiving the Electronic Version.

If a Shareholder's duly completed and signed Reply Form is not received by the Company on or before 14 February 2019, such Shareholder will be deemed to have elected the Electronic Version instead of the Printed Version.

• 2. For those Shareholders who have elected (or are deemed to have elected) the Electronic Version, the Company will, on the same day when the Printed Version is mailed, notify the relevant Shareholders of the publication of such Corporate Communication on the Company's website (i) by e-mail to the e-mail address provided in the Reply Form, or (ii) if no e-mail address is provided, by a letter of notification to be mailed to such Shareholder's address as appearing in the Company's register of members.

  The notification will provide the information on where to access the relevant Corporate Communication posted on the Company's website. If, for any reason, a Shareholder who has elected (or is deemed to have elected) the Electronic Version has difficulty in accessing the Corporate Communication electronically, or wish to receive printed copies, the Company will, upon request, send the Printed Version to the Shareholder free of charge.

• 3. For those Shareholders who have elected the Printed Version, the Company will send their selected language version(s) of the Corporate Communication together with a letter (the "Second Letter") and a change request form (the "Change Request Form"), prepared in English and Chinese, with a prepaid mailing label for posting within Hong Kong to them. The Second Letter specifies that the Corporate Communication prepared in the other language will be available upon request, and that Shareholders may change their language choice and means of receipt of future Corporate Communications by completing the Change Request Form and returning it to the Share Registrar.

• 4. For future Shareholders, they will, for the first time, receive a printed copy of the Corporate Communication in both English and Chinese together with a letter similar to the First Letter and the Reply Form for them to confirm the future channel of communication with the Company.

• 5. Shareholders can at any time by giving at least a 7-day notice in writing to the Share Registrar or by e-mail [e-mail] change their choice of communication channel or language(s).

• 6. All Corporate Communications in both English and Chinese are available on the HKEx's website and the Company's website atwww.chinaunicom.com.hk.Investors who are interested in receiving information about the Company may register on the Company's website, and upon successful registration, will receive alerts when the Company published the Corporate Communications on the Company's website.
