Explanatory Note:

Effective on January 17, 2023, Euro Tech Holdings Company Limited (the “Registrant”) has appointed J&S Associate (“J&S”) as its independent registered public accounting firm for the fiscal year ending December 31, 2022. The Registrant has terminated the services of the Registrant’s previous independent auditor, Union Power HK CPA Limited (“Union Power”) effective on January 11, 2023. J&S is headquartered in Malaysia and will be subject to the inspections by the Public Company Accounting Oversight Board of the United States. The appointment of J&S was made after careful consideration and evaluation by the Registrant and has been approved by the Audit Committee and the Board of Directors of the Registrant.

During the Registrant’s two most recent fiscal years ended December 31, 2021 and 2020, through the termination of services of Union Power on January 11, 2023, there were no disagreements between the Registrant and Union Power on any matter of accounting principles or practices, financial statement disclosure, or auditing scope or procedure, which disagreements, if not resolved to the satisfaction of Union Power, would have caused it to make reference to the subject matter of the disagreements in connection with its report on the Registrant’s consolidated financial statements for such periods. In addition, Union Power’s reports on the financial statements as of and for the years ended December 31, 2021 and 2020 did not contain an adverse opinion or disclaimer of opinion and were not qualified or modified as to uncertainty, audit scope or accounting principles. During the fiscal years ended December 31, 2021 and 2020 through the termination of services of Union Power on January 11, 2023, there were no “reportable events” as that term is defined in Item 16F(a)(1)(v) of Form 20-F.

During the two most recent fiscal years ended December 31, 2022 and 2021 and any subsequent interim period prior to engaging J&S, neither the Registrant nor anyone on its behalf consulted J&S regarding either (i) the application of accounting principles to any proposed or completed transaction, or the type of audit opinion that might be rendered on the Registrant’s financial statements, and neither a written report nor oral advice was provided to the Registrant that J&S concluded was an important factor considered by the Registrant in reaching a decision as to any accounting, auditing or financial reporting issue; or (ii) any matter that was either the subject of a disagreement (as defined in Item 16F(a)(1)(iv) of Form 20-F and the related instructions to Item 16F of Form 20-F) or a reportable event.

The press release is attached as Exhibit 99.1 to this Current Report on Form 6-K.
