On September 20, 2016, Nutrastar International Inc. (the “Company”) received a letter from Crowe Horwath (HK) CPA Limited (“Crowe Horwath”) resigning as the Company’s principal accountant to audit the Company’s financial statements.

Crowe Horwath’s reports on the Company’s financial statements for the years ended December 31, 2014 and 2013 did not contain an adverse opinion or a disclaimer of opinion, and was not qualified or modified as to uncertainty, audit scope, or accounting principles. Crowe Horwath has not audited and reported on the Company’s financial statements for the year ended December 31, 2015.

During the years ended December 31, 2015 and 2014, and through Crowe Horwath’s resignation on September 20, 2016, there were (1) no disagreements with Crowe Horwath on any matter of accounting principles or practices, financial statement disclosure, or auditing scope or procedures, which disagreements, if not resolved to the satisfaction of Crowe Horwath, would have caused Crowe Horwath to make reference to the subject matter of the disagreements in connection with its reports, and (2) no events of the type listed in paragraphs (A) through (D) of Item 304(a)(1)(v) of Regulation S-K.

The Company furnished Crowe Horwath with a copy of this disclosure on September 23, 2016, providing Crowe Horwath with the opportunity to furnish the Company with a letter addressed to the Securities and Exchange Commission stating whether it agrees with the statement made by the Company herein in response to Item 304(a) of Regulation S-K and, if not, stating the respect in which it does not agree. A letter from Crowe Horwath, dated September 26, 2016, is filed as Exhibit 16.1 to this report.
