1. A fake AI-generated video accusing Eastroc Beverage founder Lin Muqin of refusing to drink his own company’s product wiped over $1 billion (more than 7 billion yuan) off the company’s market value within days [para. 1]. The video was later confirmed by police to be fabricated, and Eastroc’s Shanghai-listed shares recovered after the company denied the claims and authorities detained a suspect [para. 2]. The episode highlighted how quickly public concerns over health and food safety can turn into a crisis for consumer brands, especially those built around products high in sugar [para. 2].
2. The controversy began on June 22, when a short video circulated online claiming to show Lin at a private dinner, where a man identified as Lin appeared to reject a bottle of Eastroc’s flagship drink, saying: “I don’t usually drink this. I drink something else.” [para. 4] The video spread quickly, triggering questions about whether the founder avoided the drink he sold to consumers [para. 5]. Eastroc’s Shanghai-listed shares fell from 120.6 yuan to 110.9 yuan (an 8% decline) by June 26, and its Hong Kong-listed shares also dropped more than 4% [para. 6].
3. Eastroc denied the video’s authenticity on June 27, reporting the matter to police [para. 7]. A motorcycle racer and entrepreneur who attended the dinner said the clip had been edited out of context [para. 7]. On June 29, police in Shenzhen said an online content creator used AI tools to fabricate the video, and the suspect was detained on criminal charges [para. 8]. Investor sentiment quickly recovered, with Eastroc’s Shanghai-listed shares jumping 10% on June 29, regaining more than 8 billion yuan in market value [para. 9]. The fake video succeeded because it tapped into existing consumer concerns about sugary energy drinks and healthier lifestyles [para. 10].
4. Eastroc’s rise is tied to Lin Muqin, born in Guangdong in 1964, who built the company through cost discipline, aggressive pricing, and understanding of mass-market consumers [para. 11]. In 1997, he joined a struggling state-owned beverage company in Shenzhen [para. 12]. In 2003, during China’s state-owned enterprise restructuring, Lin and employees invested 4.6 million yuan to acquire the company and transform it into a privately controlled firm [para. 13]. He identified an opening for a cheaper energy drink alternative to Red Bull, targeting workers and drivers [para. 15].
5. In 2009, Eastroc launched its flagship drink in plastic bottles with protective caps, priced at about 3.5 yuan, designed for outdoor workers [para. 16]. By 2019, it captured about 15% of China’s energy drink market, ranking second behind Red Bull and becoming the largest domestic brand in the category [para. 17]. To attract younger consumers, Eastroc linked the brand with major sporting events, such as becoming the official functional beverage of the King Pro League and the Hangzhou Asian Games in 2022 [para. 19].
6. Eastroc has shown ability to turn trends into marketing opportunities. In November 2025, professional motorcycle racer Zhang Xue sought sponsorship; after social media calls, Eastroc became a sponsor in January 2026 and upgraded to global title sponsorship in April 2026 [para. 20]. The company works with more than 3,200 distributors and reaches over 4.3 million retail outlets nationwide [para. 22]. Lin also expanded into lower-sugar and sugar-free products, coffee, and tea beverages [para. 23]. In 2025, Eastroc reported revenue of 20.9 billion yuan (up 31.8%) and net profit of 4.4 billion yuan (up 32.7%) [para. 23].
7. Eastroc faces a challenge from changing consumer attitudes toward sugar [para. 24]. In April, a canned product featuring “0 Sugar” drew criticism; Eastroc said the wording was a registered trademark and the product complied with national standards, but critics argued the packaging could mislead consumers [para. 24]. A 2024 test found that a 500-milliliter bottle of Eastroc’s flagship drink contained 66.5 grams of sugar, equivalent to about 14.6 sugar cubes [para. 25]. The Chinese Nutrition Society’s 2022 guidelines recommend a daily sugar limit of 25 grams, meaning one bottle exceeds the recommended limit [para. 25]. Eight of Eastroc’s 12 functional beverages contained over 25 grams of sugar per bottle, sparking concerns about excessive sugar intake [para. 26]. These concerns, combined with the AI video incident, highlight Eastroc’s challenge of balancing profitability and consumer trust as demand for healthier products rises [para. 26].
