BEIJING, June 11, 2018 /PRNewswire/ -- Sinovac Biotech Ltd. (NASDAQ: SVA) ("Sinovac" or the "Company"), a leading provider of biopharmaceutical products in China, today announced that the company has relaunched its website, at www.sinovacbio.com.

On April 30, 2018, the Company temporarily blocked access to its websites upon discovering that Aihua Pan, the Chairman of the Board of the Company's controlled Chinese subsidiary, Sinovac Biotech Co., Ltd. ("Sinovac Beijing"), who was appointed by Sinobioway Biomedicine Co., Ltd. ("Sinobioway"), the minority shareholder of Sinovac Beijing, inappropriately and without authorization seized control of the Company's websites.
