Re: Registration Statement on Form S-3

Ladies and Gentlemen:

We have examined the registration statement on Form S-3ASR (No. 333-204761) (“the Registration Statement”), filed on June 5, 2015 by China Biologic Products, Inc., a Delaware corporation (the “Company”), with the Securities and Exchange Commission (the “Commission”) in connection with the registration pursuant to the Securities Act of 1933, as amended (the “Act”), of the Securities (as defined below).

The Registration Statement relates to the proposed issuance and sale by the Company, from time to time, pursuant to Rule 415 under the Act, of shares of the Company’s common stock, $0.0001 par value per share (the “Common Stock”), shares of the Company’s preferred stock, $0.0001 par value per share (the “Preferred Stock”), warrants to purchase any of the securities described above (the “Warrants”), and units consisting of Common Stock, Preferred Stock, and/or Warrants in any combination (the “Units”). The Registration Statement also relates to the proposed sale by certain selling stockholders to be identified in a Prospectus Supplement (as defined below) (the “Selling Stockholders”), from time to time, pursuant to Rule 415 under the Act, of shares of Common Stock (the “Selling Stockholder Securities,” and together with the Company Securities referred to herein as the “Securities”). The Securities are to be sold from time to time as set forth in the Registration Statement, the prospectus contained therein (the “Prospectus”) and the supplements to the prospectus referred to therein (each a “Prospectus Supplement”).

We understand that 3,000,000 shares of Common Stock of which 700,000 shares are to be sold by the Company and 2,300,000 shares are to be sold by the Selling Stockholders, plus an option to purchase up to an additional 450,000 shares of Common Stock granted to the underwriters of which 105,000 shares are to be sold by the Company and 345,000 shares are to be sold by the Selling Stockholders (collectively, the “Shares”), to the underwriters for resale to the public as described in the Registration Statement as well as the Prospectus Supplement, dated as of June 5, 2015, relating to the offering of the Shares thereto, and pursuant to an underwriting agreement (the “Underwriting Agreement”), dated as of June 10, 2015, by and among the Company, the Selling Stockholders and the representatives on behalf of the several underwriters named therein, which is to be filed as an exhibit to the Company’s Current Report on Form 8-K.

As legal counsel to the Company and the Selling Stockholders with respect to matters in connection with the public offering, we have examined copies of the Underwriting Agreement, the Registration Statement, the Prospectus that forms a part thereof and the Prospectus Supplement thereto related to the offering of the Shares, which was dated as of June 5, 2015 and was filed by the Company in accordance with Rule 424(b) promulgated under the Securities Act of 1933. We have also examined instruments, documents and records which we deemed relevant and necessary for the basis of our opinion hereinafter expressed.
