In Depth: Disputed Sinovac Chairman Struggles to Retain Control Amid Multibillion-Dollar Dividend Payouts
Listen to the full version

When talking with Caixin, Sinovac Biotech Ltd.’s Chiang Li describes himself as a scientist with a patriotic commitment to original innovation, not a capitalist. But this self-portrait contrasts starkly with his public image as a central combatant in a war for the vaccine-maker’s riches.
Two groups in various forms have vied for control of the company in a boardroom drama that stretches back nearly a decade. Li’s faction took the reins with a board installed earlier this year but was controversially ousted in July by a hotly contested move by the opposition. The long, complex story has now come to a head, with shareholders finally getting a taste of the firm’s Covid-19 windfall and billions of dollars in dividends at stake.
