PROPOSED CHANGE OF AUDITOR

This announcement is made by China Development Bank International Investment Limited (the "Company", together with its subsidiaries (the "Group")) pursuant to Rule 13.51(4) of the Rules Governing the Listing of Securities on The Stock Exchange of Hong Kong Limited (the "Listing Rules").

The board (the "Board") of directors (the "Directors") of the Company announces that as the Company intends to appoint an auditor under the same international network as China Development Bank Capital Corporation Ltd., the intermediate controlling shareholder of the Company (together with its subsidiaries, "CDBC Group"), PricewaterhouseCoopers ("PwC") Limited will retire as the auditor of the Company at the conclusion of the forthcoming annual general meeting of the Company (the "AGM") to be held on 23 June 2021. On 11 May 2021, the Board has resolved, with the recommendation of the audit committee of the Company, to propose the appointment of BDO Limited ("BDO") as the new auditor of the Company (the "Proposed Appointment") after the retirement of PwC and to hold office until the conclusion of the 2021 annual general meeting of the Company, subject to the approval by the shareholders of the Company (the "Shareholders") at the AGM and client acceptance procedures to be conducted by BDO. The Board is of the view that the Proposed Appointment would be in the interests of the Company and the Shareholders as a whole to align the audit arrangements between CDBC Group and the Company and enhance the efficiency of the audit services.

The Company is incorporated under the laws of Cayman Islands and to the knowledge of the Board there is no requirement under the laws of Cayman Islands for the retiring auditor to confirm whether or not there is any circumstance connected with their retirement which they consider should be brought to the attention of the Company's members and creditors. PwC has therefore not issued such confirmation. The Board has confirmed that there are no matters in respect of the proposed change of auditor that need to be brought to the attention of holders of securities of the Company.

A supplemental circular containing details of the proposed change of auditor together with the supplemental notice of AGM and the revised form of proxy for AGM will be despatched to the Shareholders in due course.
