Rong’an County, in China’s Guangxi Zhuang Autonomous Region, is experiencing a remarkable economic transformation, fueled by a slight, sweet citrus fruit known locally as “jinju,” or golden orange – the kumquat. Once a seasonal treat, the Rong’an kumquat has become a nationally recognized brand and a key driver of rural prosperity, boosted recently by an unexpected endorsement from a tech industry titan. The story of this fruit is one of innovation, strategic branding, and a savvy embrace of the digital marketplace, transforming a poverty-alleviation initiative into a multi-billion yuan industry.
The surge in popularity for Rong’an kumquats gained significant momentum in late January when Nvidia founder and CEO Jensen Huang was filmed carrying armfuls of the fruit from a Shanghai wet market. He reportedly distributed them at his China office’s year-end party, a gesture that resonated powerfully in Rong’an, some 1,600 kilometers southwest. While many shoppers at the market didn’t recognize Huang, the endorsement proved invaluable for the local kumquat industry.
Unlike many citrus fruits known for their tartness, Rong’an kumquats are prized for their sweetness, thin skin, and the fact that the entire fruit is edible. In Chinese culture, kumquats symbolize good luck and prosperity, making them a popular gift and decoration during the Lunar New Year. This cultural significance, combined with the fruit’s unique flavor profile, has contributed to its growing appeal both domestically and internationally.
From Poverty Alleviation to Global Export
The rise of the Rong’an kumquat is rooted in a local poverty-alleviation drive that evolved into a technology-driven industry. By 2025, Rong’an County had 231,000 mu (approximately 15,400 hectares) dedicated to kumquat cultivation, yielding roughly 287,000 tonnes of fruit annually. The industry’s total value reached nearly 10 billion yuan (around $1.45 billion USD), establishing “Rong’an Kumquat” as a nationally recognized brand. More than 100,000 residents now depend on the kumquat industry for their livelihoods, encompassing planting, processing, and logistics.
The Role of Technology and Quality Control
Driving this transformation is a new generation of entrepreneurs who have returned to Rong’an to apply modern techniques to traditional agriculture. Wei Xiaodong, founder of Guangxi Rongan Ant Agriculture Development Co., Ltd., established in 2017, exemplifies this trend. His company prioritizes technology and stringent quality control measures throughout the production process.
Inside the company’s packing facility, the sorting process resembles a high-tech laboratory. An artificial intelligence (AI) system scans each kumquat for appearance, color, surface defects, and internal qualities, including sugar content, with all data tracked and monitored in real-time. “Manual sorting sometimes misses fruit that looks perfect but lacks sweetness,” Wei explained. “The AI performs a complete internal and external check-up, ensuring every batch meets our standards.”
Premium-grade kumquats, approximately 20 pieces per kilogram, are individually wrapped in food-grade preservative film, a labor-intensive process designed to extend shelf life and prevent spoilage. Wei reported that the company’s export volume roughly doubled in the past year.
A Unique Microclimate and the ‘Crisp Honey’ Variety
The exceptional quality of Rong’an kumquats isn’t solely attributable to technology; it’s similarly rooted in the region’s unique environmental conditions. According to Wu Qiqian, director of the government-backed Rong’an Kumquat Research Institute, the area’s high humidity (around 75 percent) and clean water sources have fostered the development of a distinct kumquat variety. “In harsher conditions, kumquats tend to develop thorns, seeds, and thick, bitter skins as defenses,” Wu said. “Here, the fruit evolved to shed those protections.”
Over decades, Rong’an kumquats have become thornless with exceptionally thin, edible skins. The pinnacle of this evolution came in 2007 with the discovery of a mutant tree producing the now-prized “Crisp Honey” kumquat – seedless, thin-skinned, and intensely sweet. Researchers at the institute spent over a decade refining cultivation techniques, achieving large-scale production of the high-sugar variety by 2021 without compromising its delicate nature.
Protecting the Brand and Expanding Reach
To ensure consistent quality, Rong’an has implemented strict national standards across all stages of production, from planting and harvesting to cold-chain logistics. This “field-to-table” model is powered by a big data platform that tracks growth in real-time. Wei Xiaodong’s company operates its own pesticide-residue testing laboratory, conducting inspections at both the orchard and the factory, rejecting any loads that fail to meet standards. The company currently operates a 5,800-mu eco-friendly production base and is preparing to meet even stricter international requirements.
Current export destinations include Thailand, Vietnam, Singapore, Malaysia, Indonesia, Canada, and Qatar. In 2025, county-wide kumquat exports reached 6.34 million yuan – nearly four times the previous year’s total. Local authorities are actively protecting the “Rong’an” name as intellectual property and leveraging China’s growing e-commerce sector to maintain the fruit’s viral momentum. Lai Yuanyuan, a local businesswoman and former fruit farmer, noted, “Rong’an kumquat isn’t just a fruit; it is a product designed for the digital age. It is naturally suited for e-commerce: resilient during transport and possessing a long shelf life.”
A recent collaboration between Ferrero, the Italian chocolatier, and Pagoda, a Chinese fruit retail giant, further elevates the product’s appeal, upgrading the packaging from simple plastic crates to luxury chocolate-box style presentation.
Looking ahead, Rong’an County is focused on maintaining and enhancing the quality of its kumquats to meet the demands of increasingly sophisticated markets. The success story of the “golden orange” demonstrates the potential for rural revitalization through innovation, strategic branding, and a commitment to quality.
